Jackie used to be on the phone 3 1/2 times as her brother. her parents threatened her to take away the phone, so she cut down to 2/5 of the time she used to be on the phone. how many times as much as her brother is jackie now on the phone?

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.
