Question

Как к 2 целым прибавить 4/17? Как к 17 целым прибавить 9/13? Как из 4 целых вычесть 3/5? Как из 15 вычесть 6/7? Как из 3 целых 1/5 вычесть 1 целую 3/5? Как из 2 целых 4/9 вычесть 1 целую 7/9?

Answer 1

1)  17+9/13=17/1+9/13=221/13+9/13=230/13=17  9 /13
2)  4-3/5=4/1-3/5=20/5-3/5=17/5=3  2/5
3)  15-6/7=15/1-6/7=105/7-6/7=99/7=14  1/7
4)  3  1/5 - 1  3/5=2  6/5 - 1  3/5=1  3/5
5)  2  4/9  -  1  7/9=1  13/9 - 1  7/9= 6/9=2/3

Adding Fractions to Whole Numbers:

To add a fraction to a whole number, you can convert the whole number to a fraction with the same denominator as the fraction and then add the two fractions together.

Adding 4/17 to 2 as a whole number: To add 4/17 to 2 as a whole number, convert 2 to a fraction with a denominator of 17 and then add the two fractions together. - 2 as a fraction with a denominator of 17 is 34/17. - Adding 4/17 to 34/17 gives 38/17, which is equal to 2 2/17.

Adding 9/13 to 17 as a whole number: To add 9/13 to 17 as a whole number, convert 17 to a fraction with a denominator of 13 and then add the two fractions together. - 17 as a fraction with a denominator of 13 is 221/13. - Adding 9/13 to 221/13 gives 230/13, which is equal to 17 13/13 or 18 -3/13.

Subtracting Fractions from Whole Numbers:

To subtract a fraction from a whole number, you can convert the whole number to a fraction with the same denominator as the fraction and then subtract the two fractions.

Subtracting 3/5 from 4 as a whole number: To subtract 3/5 from 4 as a whole number, convert 4 to a fraction with a denominator of 5 and then subtract the two fractions. - 4 as a fraction with a denominator of 5 is 20/5. - Subtracting 3/5 from 20/5 gives 17/5, which is equal to 3 2/5.

Subtracting 6/7 from 15 as a whole number: To subtract 6/7 from 15 as a whole number, convert 15 to a fraction with a denominator of 7 and then subtract the two fractions. - 15 as a fraction with a denominator of 7 is 105/7. - Subtracting 6/7 from 105/7 gives 99/7, which is equal to 14 1/7.

Subtracting 1 3/5 from 3 as a whole number: To subtract 1 3/5 from 3 as a whole number, convert 3 to a fraction with a denominator of 5 and then subtract the two fractions. - 3 as a fraction with a denominator of 5 is 15/5. - Subtracting 1 3/5 (or 8/5) from 15/5 gives 7/5, which is equal to 1 2/5.

Subtracting 1 7/9 from 2 as a whole number: To subtract 1 7/9 from 2 as a whole number, convert 2 to a fraction with a denominator of 9 and then subtract the two fractions. - 2 as a fraction with a denominator of 9 is 18/9. - Subtracting 1 7/9 (or 16/9) from 18/9 gives 2/9, which is equal to 2 2/9.
