Put together the whole solution.
481 ÷ 18 is equal to 10 + 10 + 5 + 1 with a remainder.
481 divided by 18 is ______ remainder ______ .
To solve the problem, we need to find out how many times 18 can be subtracted from 481 and what the remainder is.
Let’s break it down step by step:
1. Subtract 18 multiple times:
– 481 – 180 = 301 (18 × 10)
– 301 – 180 = 121 (18 × 10)
– 121 – 90 = 31 (18 × 5)
– 31 – 18 = 13 (18 × 1)
– 13 is less than 18, so we stop here.
2. Count the total subtractions:
– We did 10 (from 480 to 300), another 10 (from 300 to 120), 5 (from 120 to 30), and 1 (from 30 to 13). That’s:
– 10 + 10 + 5 + 1 = 26.
3. Calculate the remainder:
– After subtracting 18 a total of 26 times, we get:
– 481 – 468 = 13 (the total of 18 * 26, which equals 468).
– Thus, the remainder after dividing 481 by 18 is 13.
Putting this all together, we find:
481 ÷ 18 is equal to 26 remainder 13.
So, filling in the blanks:
481
