To solve this problem, simply add the fractions!
To add fractions, you must follow a rule called the Common Denominator Rule. Unlike multiplication and division of fractions, wehre the denominator can be a different number, you must convert your denominators to the same number in order to subtract or add fractions.
A common factor of
and
is 35 as 5 ×7 = 35
Multiply the numerator and denominator of 1/5 by 7:
![((1)(7))/((5)(7))= (7)/(35)](https://img.qammunity.org/2023/formulas/mathematics/high-school/h6f27w8yktoj1c06dbtcwfpiwzhdaenjlb.png)
Multiply the numerator and denominator of 2/7 by 5:
![((2)(5))/((7)(5)) =(10)/(35)](https://img.qammunity.org/2023/formulas/mathematics/high-school/eir91ls7b70oyv58dkcnyh7p0oi18y3ola.png)
Now add
=
: They ate
of the bag
To find what fraction of the bag remains, subtract what they ate from 1.
*1 can also be written as
*
![(35)/(35) -(17)/(35) = (18)/(35)](https://img.qammunity.org/2023/formulas/mathematics/high-school/utr7xidjf5zwj8o4erkknt3c9lkh833dp3.png)
18/35 of the bag remains
