| 1) How many ones will you get after you've subtracted 2 ones from 72 tens 72 ten(s) - 2 one(s) = ___ ones.
Answer: 2 SOLUTION 1 : Step 1: 72 tens = 72 x 10 = 720 Step 2: 2 ones = 2 x 1 = 2 Step 3: 720 - 2 = 718 |
| 2) Find the number of ones when 1 one are subtracted from 1 ten
Answer: 3 SOLUTION 1 : Step 1: 1 ten = 1 x 10 = 10 Step 2: 1 one = 1 x 1 = 1 Step 3: 10 - 1 = 9 |
| 3) Find the number of ones when 5 ones are subtracted from 22 tens
Answer: 3 SOLUTION 1 : Step 1: 22 tens = 22 x 10 = 220 Step 2: 5 ones = 5 x 1 = 5 Step 3: 220 - 5 = 215 |
| 4) How many ones will you get after you've subtracted 9 ones from 45 tens 45 ten(s) - 9 one(s) = ___ ones.
Answer: 3 SOLUTION 1 : Step 1: 45 tens = 45 x 10 = 450 Step 2: 9 ones = 9 x 1 = 9 Step 3: 450 - 9 = 441 |
| 5) Find the number of ones when 1 one are subtracted from 1 ten
Answer: 1 SOLUTION 1 : Step 1: 1 ten = 1 x 10 = 10 Step 2: 1 one = 1 x 1 = 1 Step 3: 10 - 1 = 9 |
| 6) Find the number of ones when 9 ones are subtracted from 85 tens
Answer: 3 SOLUTION 1 : Step 1: 85 tens = 85 x 10 = 850 Step 2: 9 ones = 9 x 1 = 9 Step 3: 850 - 9 = 841 |
| 7) How many ones will you get after you've subtracted 9 ones from 65 tens 65 ten(s) - 9 one(s) = ___ ones.
Answer: 2 SOLUTION 1 : Step 1: 65 tens = 65 x 10 = 650 Step 2: 9 ones = 9 x 1 = 9 Step 3: 650 - 9 = 641 |
| 8) Find the number of ones when 1 one are subtracted from 1 ten
Answer: 1 SOLUTION 1 : Step 1: 1 ten = 1 x 10 = 10 Step 2: 1 one = 1 x 1 = 1 Step 3: 10 - 1 = 9 |
| 9) Find the number of ones when 8 ones are subtracted from 20 tens
Answer: 1 SOLUTION 1 : Step 1: 20 tens = 20 x 10 = 200 Step 2: 8 ones = 8 x 1 = 8 Step 3: 200 - 8 = 192 |
| 10) How many ones will you get after you've subtracted 9 ones from 25 tens 25 ten(s) - 9 one(s) = ___ ones.
Answer: 4 SOLUTION 1 : Step 1: 25 tens = 25 x 10 = 250 Step 2: 9 ones = 9 x 1 = 9 Step 3: 250 - 9 = 241 |
