11 by 20 plus 5 by 25​

Answer 1

Answer:

The answer is = 0.75 (or) 3/4

Step-by-step explanation:

(11/20)+(5/25)

(11/20)+(1/5)

0.55+0.2

0.75

Answer 2

To find :  $\frac{11}{20} + \frac{5}{25}$

Solution :

• To find the sum of given rational numbers we get need to equalize denominators of both the rational numbers. By taking LCM

• Therefore, LCM = $100$

• Now, multiplying numerators of both rational numbers by same number as multiplied by denominators to make LCM.
• Therefore, we get, $\frac{11}{100}+\frac{5}{100}=\frac{11 \times 5}{100}+\frac{5 \times 4}{100}$

                                                     $= \frac{55}{100} + \frac{20}{100} \\\\= \frac{55 + 20}{100} \\\\= \frac{75}{100} \\\\= \frac{3}{4}$

Hence, sum of $\frac{11}{20} + \frac{5}{25}$  is $\frac{3}{4}$ .
