Question

subtract:- 5/7 from 8/13​

Answer 1

• We have to evaluate the above expression by using the given data.

             Given data:- $\frac{8}{13} -\frac{5}{7} .$

             To find:- Value of given expression.

              Solution:-

• We know that Subtraction means taking away some value from another value.

• Subtraction is denoted by (-).

• Properties of subtraction are as follows:-

1. Subtracting a number from itself.
2. Subtracting 0 from a number.
3. Order property.
4. Subtraction of 1.

       Therefore,

        $\begin{array}{l}\frac{8}{13}-\frac{5}{7} \\\\=\frac{8 \times 7}{13 \times 7}-\frac{5 \times 13}{7 \times 13} \\\\=\frac{56}{91}-\frac{65}{91} \\\\=\frac{56-65}{91} \\\\=-\frac{9}{91}\end{array}$

      Hence we will get the value is $-\frac{9}{91} .$

Answer 2

Answer:

-9/91 is answer.

Step-by-step explanation:

5/7 and 8/13 are unlike fractions so to convert them into like fractions we have to find the LCM of their denominators 7 and 13. Their LCM is 91. now to convert them=5*13/7*13=65/91 and 8*7/13*7=56/91. now 56/91-65/91 will result in negative fraction that is 56-65/91=-9/91.
