it took jake 28 minutes to run 5km last months. this month he ran 5km in 21 minutes. by what percentage had jake improve his running time?

25%

Step-by-step explanation:

28-21=7

7/28=×/100

7×100=700

700÷28=25

7

Step-by-step explanation:

Okay so, 28-21 =07 right

7 as a percent is 700% and the limit is 100%

so 700%/100%= 7

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
