1. 1. Find the product of 8/10 and 4/7.

• 32/70

• 1 3/5

• 12/17

• 16/35

Answer explanation

8 x 4 = 32 and 10 x 7 = 70.

Simplify 32/70, which is 16/35.

2. 2. Find the difference of 5/12 and 1/6.

• 18/72

• 7/12

• 1/4

• 42/72

Answer explanation

We can use cross multiplication.

5 x 6 = 30, 12 x 1 = 12 and 12 x 6 = 72.

30 - 12 = 18, and we have 18/72.

Simplify = 1/4.

5. 6. Jane ordered 4 pounds of flour that can make 20 cakes. If she would have ordered 12 pounds of flour, how many cakes can it make?

• 50 cakes

• 48 cakes

• 32 cakes

• 60 cakes

Answer explanation

We can use cross multiplication.

20 x 12 = 240 and 4 x n = 4n.

240 / 4 = 60, so, n = 60.

7. Third Quarter

8. 7. Multiply +7 by the absolute value of -13.

• -20

• +20

• +91

• -91

Answer explanation

The absolute value of -13 is 13.

So, +7 x +13 = 91, since they are like signs, the answer is positive (+91).

8. 8. Translate "a number n plus forty-nine".

• n + 49

• 49 + n

• 49n

Answer explanation

"A number n" means n.

"Plus" means +.

And "forty-nine" means 49.

It becomes n + 49.

9. 9. What is 5m - 7² + (36 ÷ y) - (if m = 10, y = 6)?

• 7

• 12

• 73

• 10

Answer explanation

M = 10, so 5 x 10 = 50, 50 divided by 7² or 49 equals to 1.

In the parenthesis, 36 divided by y or 6 equals to 6.

And 1 + 6 equals 7.

10. 10. "2, 5, 8, 11, 14, 17..." What is the 15th

11. term in this sequence?

• 84

• 44

• 19

• 46

Answer explanation

Remember: A_n = A₁ + d (n - 1)

A₁ = 2, D = 3, n = 15

15 - 1 = 14, 14 x 3 = 42

42 = 2 = 44
