Math Practice Questions

Convert the following written statements to mathematical:

1) 3 less the fish John had is 18.
2) Matt is a quarter of his dad's age, his dad's age is 48.
3) The dog is three times older then Annie, her age is 15.
4) Jane's height is three times less than her brother's height, his height is 6.
5) The phone calls from yesterday was 9 times more today and the calls were 108.

Solve the following algebric equations:

1) 5n = 200
2) n + 26 = 40
3) 2n - 27 = 11
4) n + 5 = 18
5) 2n + 18 = 26

Hope these questions will help you!

Number of the Day

1. Divide the number by two.

2. Expanded Form. (Eg. 1000+200+30+4+0.5+0.06+0.007+1234.567

3.Write the number in words. (Eg. One thousand, two hundred, thirty-four and five hundred sixty-seven thousandths)

4.Round to the nearest hundred. (01234 the hundred stays, 56789 it goes up)

5.What digit is in the tenths place. (For this, it's important to know your place value

6. Double the number. (x2)

7. Find the Circumference. (use the formula: C=2(pi)r)

8. Make a power. ( n*: n is the base, the star is the exponent)

9. Make the power in factored form (the power you did for #8). (Eg. 4x4x4x4x4=1240)

10. Cube the in the ones place. (n*: n is the digit in the ones place, the star is the exponent for cube)

11. Square the in the hundreds place. (n*: n is the digit in the hundreds place, the star is the exponent for squared)

12. Use calculator and round to the nearest hundredth.

13. The product of all the digit. (1x2x3x4x5x6x7=5040. If there is a zero in the number the product is 0)

14. Prime Numbers in the Number of the Day. (Numbers with 2 factors, one and its self)

15. Find the area. (Use the formula: A=(pi)r(squared))

16. Use the divisibility rules.

17. Find the prime factors.

18. Use integer notes.

19. Use subtracting integer notes.

20. Create a fraction.

21. Create an improper fraction.

22. Create a mixed fraction.

23. Convert into a decimal.

24. Create a picture for #21.

25.Convert answer to #21 into a percent.

My Answer to a Probability Question

Question:

In a bakery, they sell five different types of cupcakes: Chocolate, Vanilla, Carrot Banana, and Strawberry. One sunny afternoon, a young girl, a young man, and an old woman came into the bakery. The one they buy can be one of these five cupcakes.

a) Draw a Tree Diagram or a Chart, to show the sample space.


Answer:

My Probability Question

by Madeline







Joanne picks one of five marbles in the box. In that box there is a blue marble, a green marble, a red marble, a white marble and a yellow marble. After she picks a marble, she rolls a six sided die.

a) Draw/make a tree diagram or a table to organize these two events.

b) What is the sample space for this experiment?

Texbook (1-3)

1. Explain why the area of a rectangle and the area of a parallelogram made from the rectangle are the same. Include diagrams with your answer.

If you take the triangle and move it over to where it fits, it's still the same shape, just at a different angle.

2. Deepa determined the area of this parallelogram to be 5cm².

a) Deepa did 2.5 x 2 which is 5. Deepa was supposed to find the height which the height was 2 cm. b) b x h = 4 cm 2cm x 2cm = 4 cm²




3. These parallelograms are drawn on centimeter grid paper. What is the area of each parallelogram?


a) 3cm²

b) 6 cm²

Order of Operations

B- brackets ~ ( )

E- exponents ~ 3²
D- division ~ ÷
M- multiplication ~ x
A- addition ~ +
S- subtraction ~ -

e.g: the picture above

1. Annie has been asked to calculate 1.7 + 6 ÷ 2. She claims the answer is 3.85. Do you agree? Explain why or why not.

No, I do not agree with Annie's answer. Annie probably did 1.7 + 6 = 7.7 ÷ 2 = 3.85, but her answer is right. Annie should have done 1.7 + (6 ÷ 2), which is 1.7 + 3 = 4.7

2. Put brackets in the following expression to get the largest value possible; 3 × 2.8 + 6.4 ÷ 4. What problem solving strategy did you use?

3 × 2.8 + 6.4 ÷ 4 =

(3 × 2.8) + (6.4 ÷ 4) =

8.4 + 1.6 =

= 10

3. Create a problem that could be solved using the following expression.

2.5 + 1.25 + 5 x 1.6

Question:

Anna and Jake calculated 2.5 + 1.25 + 5 x 1.6. Anna got 14, and Jake got 11.75. How do you think they got their answer? Who has the right answer?

Answer(my answer):

I think that Anna did the question like this:

2.5 + 1.25 + 5 x 1.6 = 14

I think that Jake did this:

(2.5 + 1.25) + (5 x 1.6) =

3.75 + 8 =

11

Jake added brackets so that he can make it easier.

What's your answer?
