what is 1 6/7 -1 4/11

Sagot :

LCD = 77
1 66/77 - 1 28/77= 38/77
Convert both numbers to improper fractions, and to do that, multiply the denominator and whole number, and add the numerator.

If done correctly, you should get 13/7 - 15/11.

Now, we have to find the LCM of both denominators.
77 is the LCM.

77 is the LCM.

You needed to multiply 7 by 11 to get 77, so multiply 13 by 11, too.
13 x 11 = 143
We get 143/77.

Do the same with the other fraction.
You needed to multiply 11 by 7 to get 77. So multiply 15 by 7.
15 x 7 = 105
We get 105/77

Now you can subtract.

143/77 - 105/77 = 38/77
