The value of the expression –5.45 + 4.12 –8.66 is A) -9.99
Simplify. 7 2/3+−5 1/4
To simplify 7 2/3 + -5 1/4, we can convert the mixed numbers into improper fractions and then perform the addition:
7 2/3 = (7 * 3 + 2) / 3 = 23/3
-5 1/4 = (-5 * 4 + 1) / 4 = -19/4
Now we can add the fractions:
23/3 + (-19/4) = (23 * 4 - 19 * 3) / (3 * 4) = (92 - 57) / 12 = 35/12
So, the simplified expression is 35/12.
7 2/3 = (7 * 3 + 2) / 3 = 23/3
-5 1/4 = (-5 * 4 + 1) / 4 = -19/4
Now we can add the fractions:
23/3 + (-19/4) = (23 * 4 - 19 * 3) / (3 * 4) = (92 - 57) / 12 = 35/12
So, the simplified expression is 35/12.
