X: 14= 7: 8 can someone solve this for me and explain me

x:14 = 7:8

x:14 = x/14

7:8 = 7/8

x/14 = 7/8

Multiply the numerator of the 1st ratio with the denominator of the 2nd.

And multiply the numerator of the 2nd ratio with the denominator of the 1st.

Doing so, we get -

x * 8 = 7 * 14

So, 8x = 7 * 14

8x = 98

We divide 98 by 8 (transposition method)

x = 98/8

Therefore, x = 12.25

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
