Hello!
The answer to your problem is 3 18/19
Turn 7 1/2 into an Improper Fraction
Multiply 7*2 and get 14. Now add 1 and get 15 (Denominator stays the same)
7 1/2 = 15/2
Turn 1 9/10 into an Improper Fraction
Multiply 1*10 and get 10. Now add 9 and get 19 (Denomintor stays the same)
1 9/10 = 19/10
Do Keep Change Flip (KCF)
Keep: 15/2
Change: ÷ into ×
Flip: 19/10 into 10/19
Your New Problem Should be: 15/2*10/19
Multiply
15/2*10/19= 150/38
Turn 150/38 into a Mixed Number
150/38 = 3 18/19
