It took 5 hours to mow 4 lawns. at that rate, how long will it take to mow 7 lawns?

So you divide 5 by 4 and get 1 2/5 so then multiply that by 7:) hope it helps tell me if I'm wrong

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.
