Answer:
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!!!
