3/4 + 2/3 using fractions

Step-by-step explanation:

Lowest common multiple (LCM) of 4 and 3 = 12.

Therefore 3/4 + 2/3

= 9/12 + 8/12

= 17/12 or 1 5/12.

1 5/12

Step-by-step explanation:

To do this, we need to find the LCM of 4 and 3. The LCM of 4 and 3 is 12. Now, since 4x3 is 12, we multiply 3/4 by 3/3 to get 9/12. Now, we multiply 2/3 by 4/4 (since 3x4 is 12) to get 8/12. Now, we add only the top numbers to get 17/12. To simplify this, we divide 17 by 12 (check attached screenshot). The quotient (the answer) becomes the whole number, the divisor (12) becomes the denominator, and the remainder (5) becomes the numerator. This gets us 1 5/12.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

b. is true. hope this . happy
