Question

90% of 40 test problems correctly. How many problems did

Answer 1

Answer:

30

Explanation:

Answer 2

Answer: 36 out of 40 questions would be the right answer because 90% of 40 would be 36

Chart:

10% of 40: 4

20% of 40: 8

30% of 40: 12

40% of 40: 16

50% of 40: 20

60% of 40: 24

70% of 40: 28

80% of 40: 32

90% OF 40: 36

100% of 40: 40

Since we are going up 10% to find the answer all the way until 40, we just need to add 4 more for every 10% there is.

There is another way: You could multiply then put the decimal places

E.G: 17% of 32: 5.44

17x32=544

We just need to put the decimal places
