What is the sum of 2/5 and 1/4

1320

Step-by-step explanation:

2/5 + 1/4 = 1320 = 0.65.

13 / 20

Step-by-step explanation:

1. Add 2/5 + 1/4 = 2· 4/5 · 4 + 1 · 5/4 · 5 = 8/20 + 5/20 = 8 + 5/20 = 13/20

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, the fraction result cannot be further simplified by canceling.

In other words - two fifths plus one quarter = thirteen twentieths.

the naturalist literary movement was an extension of the realist literary movement, a movement that strove to portray life as it really was hope it

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
