1over4
there is only 1
5 over 8 :)
283/4
1/4 + 1/4 = 1+1 / 4 = 2/4 = 1/2 The denominator, number on the bottom, is the same in each fraction, so you can easily add the fractions. You can think of this problem like this. You have one quarter (.25), add another quarter (.25) and you have a half dollar (.50)
7 and 1/4 is equivalent to 725%
60 is 80% of what number:= 60 / 80= 60 / 0.8= 75
60 percent of 60 is what number?.6 x 60 = 36
if 60% of number = 621 then: number = 621 ÷ 60% = 621/(60/100) = 621×100/60 = 1035
60 is, itself, an even number.
