Talia attended a 5 -day math camp that lasted 5/6 of an hour each day. How many hours did Talia spend at the math camp?
Answer:
4 1/6 hours
Step-by-step explanation:
1 day = 5/6 hour
5 days = x
Cross Multiply
x = 5/6 × 5 days
x = 25/6 hours
x = 4 1/6 hours
Therefore, Talia spent 4 1/6 hours at camp.
When simplified, y=2(x+4)+5 equals y=2x+13
For <span>12/15=47/50, we multiply 12/15 by (1/3)/(1/3) to get 4/5. For 47/50, we multiply it by (1/10)/(1/10) to get the same denominator and 4/7/5. They are not equal.
For 16/36 and 12/27, we'll notice that 36 and 27 are both multiples of 9, so we need to get that as the denominator! Multiply 16/36 by (1/4)/(1/4) because 9 goes into 36 4 times and 12/27 by (1/3)/(1/3) due to that 27 goes into 9 3 times, we get 4/9=4/9 - these are equal!
I challenge you to get the rest of them on your own using my techniques!</span>
240,000 = 24 x 10,000 but 10,000 = 10 x 10 x 10 x 10 = 10⁴, then:
240,000 = 24 x 10⁴
Answer: A. Wed to Fri
We have a bunch of natural numbers and we're told a pair is in the ratio 2:5.
For natural numbers to have this ratio, the left number will be a multiple of two and the right number will be a multiple of five.
Our only option for a multiple of 5 is 15, Friday. So we have
2:5 = x:15
and x = 15*2/5 = 6
which was Wednesday's number. So we get Wed:Fri=6:15=2:5.
