Answer:
7/4 or 1 3/4
Step-by-step explanation:
To add fractions, they need the same denominator (a "common" denominator). Here, the fraction 3/2 can be given a denominator of 4 by multiplying numerator and denominator by 2.
3/2 · 2/2 = 6/4
Now 1/4 and 6/4 can be added:
1/4 + 3/2 = 1/4 +6/4 = (1+6)/4 = 7/4
The fraction 7/4 can be converted to a mixed number by dividing 7 by 4. The quotient is the whole number, and the remainder is the numerator of the fractional part.
7/4 = 1 remainder 3 = 1 3/4
