You paint 1/2 wall in 1/4 hour. at that rate, how long will it take you to paint one wall?

1/4 ÷ 1/2 = 1/2

1/2 an hour to paint one wall

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
