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.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
