Answer:
1 1/2
Step-by-step explanation:
3/5 + 9/10
We need a common denominator of 10
3/5 * 2/2 + 9/10
6/10 + 9/10
15/10
10/10 + 5/10
1 + 5/10
1 + 1/2
3/2 or 1.5
Multiply 3/5 by 2 to make the denominator of both fractions equal.
2 x 3/5 = 6/10
Now that the denominators are equal, add the two fractions together
6/10 + 9/10 = 15/10 = 3/2 or 1.5
3750
50*70=35005
5*50=250
