| 1) How many ones will you get after you've subtracted 9 ones from 8 tens 8 ten(s) - 9 one(s) = ___ ones.
Answer: 1 SOLUTION 1 : Step 1: 8 tens = 8 x 10 = 80 Step 2: 9 ones = 9 x 1 = 9 Step 3: 80 - 9 = 71 |
| 2) 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 |
| 3) Find the number of ones when 7 ones are subtracted from 83 tens
Answer: 4 SOLUTION 1 : Step 1: 83 tens = 83 x 10 = 830 Step 2: 7 ones = 7 x 1 = 7 Step 3: 830 - 7 = 823 |
| 4) How many ones will you get after you've subtracted 9 ones from 42 tens 42 ten(s) - 9 one(s) = ___ ones.
Answer: 1 SOLUTION 1 : Step 1: 42 tens = 42 x 10 = 420 Step 2: 9 ones = 9 x 1 = 9 Step 3: 420 - 9 = 411 |
| 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 4 ones are subtracted from 15 tens
Answer: 1 SOLUTION 1 : Step 1: 15 tens = 15 x 10 = 150 Step 2: 4 ones = 4 x 1 = 4 Step 3: 150 - 4 = 146 |
| 7) How many ones will you get after you've subtracted 5 ones from 52 tens 52 ten(s) - 5 one(s) = ___ ones.
Answer: 1 SOLUTION 1 : Step 1: 52 tens = 52 x 10 = 520 Step 2: 5 ones = 5 x 1 = 5 Step 3: 520 - 5 = 515 |
| 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 7 ones are subtracted from 46 tens
Answer: 4 SOLUTION 1 : Step 1: 46 tens = 46 x 10 = 460 Step 2: 7 ones = 7 x 1 = 7 Step 3: 460 - 7 = 453 |
