Question

19/4+11/40 as decimal expansion​

Answer 1

Answer:

I will solve this in two ways mate

1.) Converting to decimal and adding

2.) Adding and then converting to decimal

Step-by-step explanation:

1.) Converting to decimal and adding:

First, let's divide 19 by 4, then 11 by 40

19 / 4 = 4.75

11 / 40 = 0.275

= 4.75 + 0.275

= 5.025

2.) Adding and then converting to decimal

LCM of 4 and 40 is 40

19/4 x 10/10 = 190/40 [not same decimal as LCM, so we are converting it]

11/40            = 11/40 [same decimals as LCM so we let it be]

190/40 + 11/40 = 190 + 11 / 40 = 201 / 40

now let's divide 201 by 40

201 / 40 = 5.025

Both methods show same answer, hence your decimal expansion is

5.025
