A number "in tens" means what times 10 equals the number.
In terms of 86, that would mean x • 10 = 86.
To solve this, simply divide both sides by 10.
x • 10 / 10 = x
86 / 10 = 8.6
x = 8.6
There are 8.6 tens that make up 86.
A number "in ones" means what times 1 equals the number.
Since any number times 1 is itself, a number "in ones" is itself.
86 in ones is 86, there are 86 ones in 86.
If you want how many tens and ones together make up 86, then there's a different answer.
To find this, look in the place values of 86.
There is an 8 in the tens place and a 6 in the ones place.
In this case, 8 tens and 6 ones make up 86.
If you are asking if the number 86 is in tens or ones, the answer is in ones.
This is because there is a number besides 0 in the ones place, meaning the number can't be in tens.
Numbers in tens have a number in the tens place and a 0 in the ones place.
Examples of numbers in tens:
10, 20, 30, 40, 50, 60, 70, 80, 90
Examples of numbers in ones:
123, 45, 27, 98, 63, 86, any number with a number besides 0 in the ones place.
So the number 86 is in ones.
Hope this helps!
