The cost of a sweater at a clothing store was $35. The sweater went on sale at a discount of 20% off the original price. What is the sale price of the sweater?

$28

Step-by-step explanation:

First, we have to find 20% of 35.

We can do that by multiplying 0.20 by 35. (0.20 x 35)

After multiplying them, we get a product of $7.

Since the sweater went on sale and they took 20% off of the original price, we have to subtract $7 from the original price of $35. (35 - 7)

We can solve that to get us the discounted price of $28

(sorry if this is confusing but I hope it helped)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
