Answer:

63/90 = 7/10

Step-by-step explanation:

63 = 3²×7

90 = 2×3²×5

The factor of 3² is common to both numbers, so the fraction reduces to ...

... 63/90 = (3²×7)/(3²×10) = 7/10

Carey creates the table below to help him determine 75% of 36. 75% of 36 25% 25% 25% 25% One-fourth One-fourth One-fourth One-fo

alina1380 [7]

Answer:

The correct option is (A).

Step-by-step explanation:

The expression Carey is solving is:

$X=75\%\ \text{of}\ 36$

Simplify the expression as follows:

$X=75\%\ \text{of}\ 36$

$=\frac{75}{100}\times 36\\\\=\frac{3}{4}\times 36\\\\=3\times 9\\\\=27$

So, in Carey's calculation the third step is incorrect.

Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.

Thus, the correct option is (A).
