exactly divisible by 35?
1. Which least number should be added to 1000 so that 53 divides the sum exactly?​

Answer 1

Answer:

1st answer is 20

Step-by-step explanation:

2nd is You need to divide 1000 by 53 and see what the remainder is. Subtract this remainder from 53 and you have the answer you want. When you are a child you learn to multiply and divide numbers by multipliers and divisors up to about 12. As you get older and continue to enjoy numbers,you get used to multiplying and dividing by much bigger numbers. I am an old man and I can multiply and divide by numbers like 19 and 53 without having to think about it. 1007 equals 19 times 53 and this makes your question easy.
