| 1) How many ones will you get after you've subtracted 2 ones from 69 tens 69 ten(s) - 2 one(s) = ___ ones.
Answer: 2 SOLUTION 1 : Step 1: 69 tens = 69 x 10 = 690 Step 2: 2 ones = 2 x 1 = 2 Step 3: 690 - 2 = 688 |
| 2) Find the number of ones when 7 ones are subtracted from 46 tens
Answer: 2 SOLUTION 1 : Step 1: 46 tens = 46 x 10 = 460 Step 2: 7 ones = 7 x 1 = 7 Step 3: 460 - 7 = 453 |
| 3) Find the number of ones when 1 one are subtracted from 1 ten
Answer: 2 SOLUTION 1 : Step 1: 1 ten = 1 x 10 = 10 Step 2: 1 one = 1 x 1 = 1 Step 3: 10 - 1 = 9 |
| 4) How many ones will you get after you've subtracted 1 ones from 47 tens 47 ten(s) - 1 one(s) = ___ ones.
Answer: 1 SOLUTION 1 : Step 1: 47 tens = 47 x 10 = 470 Step 2: 1 ones = 1 x 1 = 1 Step 3: 470 - 1 = 469 |
| 5) Find the number of ones when 4 ones are subtracted from 45 tens
Answer: 3 SOLUTION 1 : Step 1: 45 tens = 45 x 10 = 450 Step 2: 4 ones = 4 x 1 = 4 Step 3: 450 - 4 = 446 |
| 6) Find the number of ones when 1 one are subtracted from 1 ten
Answer: 2 SOLUTION 1 : Step 1: 1 ten = 1 x 10 = 10 Step 2: 1 one = 1 x 1 = 1 Step 3: 10 - 1 = 9 |
| 7) How many ones will you get after you've subtracted 4 ones from 89 tens 89 ten(s) - 4 one(s) = ___ ones.
Answer: 1 SOLUTION 1 : Step 1: 89 tens = 89 x 10 = 890 Step 2: 4 ones = 4 x 1 = 4 Step 3: 890 - 4 = 886 |
| 8) Find the number of ones when 3 ones are subtracted from 35 tens
Answer: 4 SOLUTION 1 : Step 1: 35 tens = 35 x 10 = 350 Step 2: 3 ones = 3 x 1 = 3 Step 3: 350 - 3 = 347 |
| 9) 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 |
