Answer:
Fraction form- 52/5
Decimal form- 10.4
Mixed number- 10 2/5
Explanation—
Multiply 4(3/5):
1. 4(3/5) is the same as (4*3)/5 because 4 and 3 are both the numerator: 4 is the same as 4/1
2. 4(3)= 12
3 12/5
Change denominator: 8+ 12/5
1. The dominator for 8 is 1 because it’s a whole number so.. = 8/1
2. Find the least common factor of 5 and 1, which is 5
3. Multiply 8/1 by the LCF (least common factor) to make both fractions have the same denominator (5)
8/1(5)= 8(5)/1(5)= 40/5
4. Add numerators: ONLY numerators because the denominator stay 5 since they are the same in both fractions
40/5 + 12/5
40+ (12) =52
5. Input new nominator:
52/5
——To find decimal, just divide the denominator by the numerator
52 ÷ 5= 10.4
