Question

find the value of (1/3+1/4+1/5) of 1200 metres​

Answer 1

Step-by-step explanation:

Solve: 7/10 + 2/5 + 3/2

Answer:

Given

710+25+32

To add two unlike fractions, first change them to the like fractions.

Find the LCM of the dinominator

LCM of 10, 5, 2 = 10

Now, let us change each of the given fraction into an equivalent fraction having 35 as the denominator.

= [(7/10) × (1/1)] = (7/10)

= [(2/5) × (2/2)] = (4/10)

= [(3/2) × (5/5)] = (15/10)

Now,

= (7/10) + (4/10) + (15/10)

= [(7 + 4 + 15)/10]

= (26/10)

= (13/5)

= 2.6
