Change these fractions to twentieths and then arrange them in order of size, smallest first.
7/20 2/5 3/4 7/10
2/5
Divide 20 by the denominator. 20/5 = 4.
Multiply the numerator by that quotient. 2 * 4 = 8
2/5 = 8/20
Try the other two fractions yourself. What do you get?
I do not now the answer to change 4:5 to twentieth
what is 3/ to twenties
Divide 20 by denominator and the answer you get will be multiplied by the numerator and the denominator will still be 20 and if you simplify the answer the should be same as the questions
This doesn’t make sense to me
I don't understand
To change fractions to twentieths, you need to find the equivalent fraction with the denominator of 20.
Let's go through each fraction one by one:
1. 7/20: This fraction is already in twentieths, so no need to make any changes.
2. 2/5: To convert this fraction to twentieths, you need to find an equivalent fraction with a denominator of 20. Multiply both the numerator and denominator by 4 to get: (2 * 4) / (5 * 4) = 8/20.
3. 3/4: To convert this fraction to twentieths, you need to find an equivalent fraction with a denominator of 20. Multiply both the numerator and denominator by 5 to get: (3 * 5) / (4 * 5) = 15/20.
4. 7/10: To convert this fraction to twentieths, you need to find an equivalent fraction with a denominator of 20. Multiply both the numerator and denominator by 2 to get: (7 * 2) / (10 * 2) = 14/20.
Now that we have converted all the fractions to twentieths, let's arrange them in order of size:
8/20, 14/20, 15/20, 7/20
So, the fractions arranged in order of size, smallest first, are:
7/20, 8/20, 14/20, 15/20
