Answer:
1) 5/7 - 2/7 = 3/7
2) 9/10 + 3/10 = 12/10 or 6/10
3) 3/4 - 2/3 = 1/1
4) 5/6 + 1/7 = 6/6 or 1
5) 9/10 - 3/10 - 2/10 = 4/10
6) 2/7 + 3/7 + 5/7 = 5/7
Step-by-step explanation:
1) Numerator:
5 - 2 = 3
Denominator:
Copy the denominator.
2) Numerator:
9 + 10 = 12
You can lowest term the numerator.
12 ÷ 2 = 6
Denominator:
Copy the denominator.
3) Numerator:
3 - 2 = 1
Denominator:
4 - 3 = 1
4) Numerator:
5 + 1 = 6
Denominator:
6 + 7 = 13
You can lowest term the denominator.
13 ÷ 2 = 2.1
Remove .1
6/6
Numerator and Denominator:
You can lowest term it again into 1.
5) Numerator:
9 - 3 = 6
6 - 2 = 4
Denominator:
Copy the denominator.
6) Numerator:
2 + 3 = 5
5 + 5 = 10
Since the numerator is higher than the denominator, the numenator should be change into lowest term.
10 ÷ 2 = 5
Denominator:
Copy the denominator.
