7 and 1/4=7+1/4
7 and 1/4-3 and 3/4=4 and 1/4-3/4 means
7+1/4-3-3/4=4+1/4-3/4 rearange
7-3+1/4-3/4=4+1/4-3/4
4-2/4=4-2/4
4-1/2=4-1/2
3 and 1/2=3 and 1/2
Answer:
31.5 hours
Step-by-step explanation:
time * speed = distance
speed=400/6=66.67 miles per hour
2100/(400/6)=31.5 hours
Answer:
90 days
Step-by-step explanation:
Let the rate per day for the 30 days period be x
Given that the rate drops to 1/3 of the rate used in 30 days period, it means that the new rate
= 1/3 x
If at a rate of x, the full tank runs for 30 days
at a rate of 1/3 x, the full tank would run for
= x/ (1/3 x) * 30 days
= 3 * 30 days
= 90 days
At the new rate, the full tank of oil will last for 90 days
Answer:
6 over 1/24
Step-by-step explanation:
You can find the quotient of 9 2/3 divided by 1 3/5 by first making the two terms into improper fractions.
To make the improper fractions, you can turn 9 2/3 into 29/3 by multiiplying 9 by the denominator (bottom number in fractions) and adding that to the numerator of 2 which gives 29.
1 3/5 can turn into 8/5.
Then you can divide using a simple trick of first organizing the data.
Currentlly it should be
29/3 divided by 8/5
Then you can flip the second fraction over.
29/3 divided by 5/8
Then you change the sign into multiplication.
29/3 times 5/8
Then you multiply like normal.
29 times 5 over 3 times 8
145 over 24
You can simplify now
6 over 1/24
Hope this helps!
