PLEASE HELP ILL MARK BRAINLIEST

convert it to improper fractions first

Step-by-step explanation:

4 x 7 + 3 = 31

So, 7   3/4 = 31/4

Similarly, 5 x 2 + 2 = 12

So, 2  2/5 = 12/5

Now we have,

31/4 - 12/5

Make the denominators same

Multiply both the denominators by each other...

4 x 5    and 5 x 4 = 20 both the denominators equal to 20.

Now multiply the numerators like that

so, 31 x 5  and 12 x 4

equals to 151/20  and 48/20

Now subtract both ...

151-48 = 103

So the answer is 103/20

Hope it helps!!!
