A
Write the sum: 1/4+ 1/4.
1/2
Write the difference: 3/4 - 1/4.
2/4 or 1/2
Add: 2/6+ 1/6. Simplify your answer.
12 (since 2/6+ 1/6= 3/6= 1/2)
Subtract: 5/8- 2/8.
3/8
Add: 1/3+ 1/6. Show how you find a common denominator and simplify.
1/2 (common denominator 6: 2/6+ 1/6= 3/6= 1/2)
Subtract: 7/10 - 2/5. Explain each step.
3/10 (convert 2/5= 4/10, so 7/10-4/10=3/10)
Add: 3/5+ 1/2. Give the answer in simplest form.
11/10= 1 1/10 (common denominator 10: 6/10+5/10=1 1/10)
Subtract: 4/9 - 1/3. Show your work and simplify.
1/9 (convert 1/3=3/9, so 4/9-3/9=1/9)
Add: 5/12+ 1/4. Show how you convert to a common denominator and simplify.
2/3 (common denom 12: 5/12+3/12=8/12=2/3)
Subtract: 11/12- 1/6. Explain each step and simplify.
3/4 (convert 1/6=2/12 and 11/12-2/12=9/12=3/4)
Add: 7/8+ 3/16. Find a common denominator and simplify.
13/16 (common denom 16: 14/16+3/16=17/16 — wait: correct step: 7/8=14/16 so 14/16+3/16=17/16=11/16)
Subtract: 5/6- 1/4. Show your common-denominator steps and simplify.
7/12 (common denom 12: 10/12-3/12=7/12)
Solve 2 1/3 + 3 1/3
5 2/3
Solve 2 1/4 + 1 1/3
3 7/12
Add: 3/4+ 5/6. Show work, find a common denominator, and simplify the final answer.
19/12= 1 7/12 (common denom 12: 9/12+10/12= 1 9/12)
Real-world problem: Maria had 7/8 of a yard of ribbon. She used 3/8 of a yard to wrap a present and then gave her friend 1/4 of a yard. How much ribbon does she have left? Show your subtraction steps and simplify.
1/8 left (Work: used 3/8+1/4=3/8+2/8=5/8; leftover 7/8-5/8=2/8=1/4
