how do i change

3.75 into a fraction


simple or improper fraction? you could say 3 and 3/4 (since .75 = 3/4) or you could go from there and convert to improper. basically simplify 375/100 (multiply 3.75/1.00 by 100/100)

but it can't be 3 and 3/4



your answer should be 15/4

then simplify 375/100

To do this (using 3 and 3/4) keep your base as 4, then to get the top, multiply the integer(3 or 3/1) by 4 (3x4) to get twelve, the add the 3 from the 3/4.

so then is this correct

for 1.5

1 1/2 1*2+1=3/2


yup you got it

  • math - ,

    the answer 15/5 is correct.

    you just had to divide both sides by 25

    '375'
    25 x 4 = 100
    25 x 12 = 300
    25 x -15- = 375

    15/ ?

    '100'
    25 x -4- = 100

    15/4 is the answer and those are the steps i used to getting that anser.
