o that's easy....it just means to do the math in your head instead of working it out on paper
you need too firstly divide the nun=numbers by each other and multiply by ten and you get your answer. I am a mathematician so this stuff is easy. glad i could help

The vocabulary word for being easy to divide mentally is "divisible." In mathematics, a number is considered divisible if it can be divided by another number without leaving a remainder. This concept is fundamental in arithmetic and plays a crucial role in various mathematical operations and problem-solving strategies.

arithmetic According to my son's homework, they are "compatible" numbers.

Numbers like 10, 25, 50, and 100 are easy to compute mentally because they have simple multiples or divisions that are easy to work with. For example, doubling 25 is 50, or dividing 100 by 10 gives you 10. These numbers are often used as benchmarks in mental math calculations.
The answer depends on your skills and your knowledge of relationships between numbers. 76/95 might look hard but it is not if you recall (from your 19 times table) that 76/95 = (19*4)/(19*5) = 4/5 = 0.8.
