Mr Tanaka used 10 gallons of gas. You find this answer by diving the denominator (3) with the total number of gallons of gas. So 15 divided by 3 is 5. Now you get the number 5, and multiply it by the numerator (2). 5*2 is 10. That is how you find the answer.
Answer: 10
Step-by-step explanation:
Divide both parts of the equation by 2:
I'm assuming your teacher wants you to calculate the speed
1/2 = 0.5
3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5
If a plane flies 840 miles in 3.5 hours, then,
speed = distance/time
speed = (840 mi)/(3.5 hr)
speed = (840/3.5) mph
speed = 240 mph
<h3>Answer: 240 mph</h3>
5 dozen= 60 doughnuts
3;43-3;27 = 16
So it took him 16 minutes for 48 doughnuts
16÷48=0,3 so one doughnut takes him 30 seconds
60×0,3=19,99=20 so it takes him about 20 minutes for 5 dozens of doughnuts
So it'll be 4;03
