3(4+7)+{5×1×4÷2+2(4-2)}
Answers
Answer:
1) 3 1/2 + 4 3/4 = 3 2/4 + 4 3/4 = 7 5/4 = 8 1/4
2) 17/3-14/5 = 85/15 - 42/15 = 43/15 = 2
13/15
Multiply:
1) 7 x 3/5 = 7/1 x 3/5 = 21/5 = 4 1/5
2) 14 x 1/4 = 14/1 x 1/4 = 14/4 = 3 2/4 = 3 1/2
3) 3 x 5 1/5 = 3/1 x 26/5 = 78/5 = 15 3/5
4) 2/3 x 2 2/3 = 2/3 x 8/3 = 16/9 = 17/9 5) 3 4/7 x 3/5 = 25/7 x 3/5 = 75/35 = 15/7
= 2 1/7
How I got my answers:
For the adding question you convert the mixed numbers into improper fractions, make them equal to the same denominator, add them, then convert them back into mixed fractions.
For the subtracting question you make them equal to the same denominator, subtract them, then I converted them into a mixed fraction.
For the multiplication questions you convert them into improper fractions, multiply the numerators by each other and the denominators by each other, then convert back to a mixed fraction.
