An automobile assembly runs for 9 3/4 hours each day. Workers work 3/4 hours shifts. How many shifts are in each day? i put 9 3/4 divided by 3/4. But that's a decimal then i tried 3/4 divided by 3/4 but thats worse. Help me please.
The answers are
B
C
C
B
D
i promise it is for connexous 100%
9 3/4 = 39/4
39/4 / 3/4 = 39/4 * 4/3
= 39/3
= 13
Thanks peppa pig I got a hundred
how is it 13 shifts
tysm i have been stuck on this test for 40 mins

It is called math my child.
To calculate the number of shifts in each day, we need to divide the total duration of the assembly run (9 3/4 hours) by the length of each shift (3/4 hours).
To divide mixed numbers, we need to convert them to improper fractions. The mixed number 9 3/4 can be written as the improper fraction (9*4 + 3)/4 = 39/4.
So, we have:
Number of shifts = (Total duration of assembly run) ÷ (Length of each shift)
= (39/4) ÷ (3/4)
When dividing fractions, we can multiply the first fraction by the reciprocal of the second fraction. Therefore:
Number of shifts = (39/4) × (4/3)
Now, we can cancel out the common factor of 4 in the numerator and the denominator:
Number of shifts = (39/1) × (1/3) = 39/3
Dividing 39 by 3, we get:
Number of shifts = 13
So, there are 13 shifts in each day of the automobile assembly.
