fraction 5 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 3 over 10
fraction 6 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 2 over 10
fraction 5 over 10 because fraction 3 over 4 minus 2 times fraction 1 over 8 equals fraction 3 over 4 minus fraction 3 over 8
Step 2: 4/5 - 2/10 GCF: multiply both sides of 4/5 by 2 = 8/10
Step 3: 8/10 - 2-10 = 6/10
