This is easy the answers 55 you just need to divide
165 ÷ 3 = ?
Step 1: Look at the multiplications of three can you make a group with an answer close to one? if not look at 16 and the multiplications of three is there a number close to 16 or exact?
Step 2: In this case 5 × 3 = 15, so 15 is close to 16.
Step 3: Now you need to subtract 16 and 15, 16 - 15 = 1.
Step 4: Like there's no number that has 1 as a answer, you need to lower the 5.
Step 5: Once you lower the five it makes 15 in the in the multiplications of three is there something close to 15 or exact? Yes there is a number that can make 15, it's 5 × 3 so 15 take away 15 makes zero so your answer will be simple, 55.
