Answer:

17.5% of 360 = 63

Step-by-step explanation:

We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.

17.5% can be break down as 10% + 5% + 2.5%

Thus,

STEP 1 : Find 10% of 360 , we get,

$\frac{10}{100} \times 360=36$

STEP 2 : find 5% of 360, we get,

$\frac{5}{100} \times 360=18$

STEP 3: find 2.5% of 360 , we get,

$\frac{2.5}{100} \times 360=9$

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360

⇒ 17.5% of 360 = 36 + 18 + 9

⇒ 17.5% of 360 = 63
