Answer:
The difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28
Step-by-step explanation:
First, to make it easier to subtract, let's change these numbers to improper fractions.
4 5/7 = 33/7
1 3/4 = 7/4
Now, we have to find the LCM (least common multiple) between 4 and 7.
4- 4, 8, 12, 16, 20, 24, 28, 32
7- 7, 14, 21, 28, 35, 42, 49
As you can see, the LCM is 28. So, lets change these fractions to have a denominator of 28.
33*4/ 7*4 = 132/ 28
7*7/ 4*7 = 49/ 28
>>132 - 49 = 83
So, the difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28
