Since 1/2 is equal to a half, you divide 50 and 40 by 2 and you'll get 25 and 20 and then you subtract 25 and 20 and you get 5 which is the answer!
Step-by-step explanation:
GIVEN
HERE
= 6+9+2+6+600÷30 { firstly add numbers }
= 623 ÷ 30
= 20
I think you understand
1/2 gallon of paint covers 1/12 of a wall
, 12 times as much paint will cover 12 times the area you can solve this by 12*1/2=6.
