Answer:
72
Step-by-step explanation:
You can find ten percent of 180 pretty easily, it is 18 (divide by 10) then multiply by 4 to get 40%.
Answer:
72
Step-by-step explanation:
10% of 180 = 180 ÷ 10 = 18
⇒ 40% = 4 x 10% = 4 x 18 = 72
Or,
convert 40% into a decimal:
40% = 40/100 = 0.4
⇒ 40% of 180 = 0.4 x 180 = 72
