Question

1. choose the lcd and the gcf for the equation below. when the fraction is in its simplest form, select gcf = 1. -1\frac{2}{3}+2\frac{3}{4} lcd = gcf =

Explanation:

Step1: Find the LCD of 3 and 4

The multiples of 3 are 3, 6, 9, 12, 15, ... and the multiples of 4 are 4, 8, 12, 16, ... The least - common multiple (LCD) of 3 and 4 is 12.

Step2: Consider the GCF of the resulting fractions in simplest form

Since we are dealing with fractions in simplest form and no non - 1 common factors will be present in the final result of the addition (after finding a common denominator and simplifying), the greatest - common factor (GCF) of the numerator and denominator of the final fraction in simplest form is 1.

Answer:

LCD = 12
GCF = 1
