True [87]

28 x because parenthesis first and you can’t do 2 + 2x so 7x times 2 is 14x and 7 times 2x is 14x

Carter used 1 1/3 gallons of paint to paint 2/5 of a wall. How many gallons will it take to paint the whole wall? Show your reas

fgiga [73]

Answer:

3 1/3 gallons

Step-by-step explanation:

It is more helpful to think of the wall as 5 sections. if two sections used 4/3, by logic one section uses 2/3 (because 4/3 ÷ 2 = 2/3). since there are 5 sections, 2/3 × 5 you get 10/3. turn it into a mixed fraction and you get 3 1/3.
