What problem is Chen checking 152x4=608+2=610
tester [92]
The +2 is a reminder to add when he multiply 4*1 (4*1=4+2=6)
4*2=8
4*5=20 (so he writes the 0 with a remainder of 2)
4*1=4+2=6
so,
152x4= 608

College A and College B made it to the state championship
timama [110]

The number of students in vans and bus are (8,22)

Step-by-step explanation:

Let the number of students in the van be “x”

Let the number of students in the bus be “y”

It is given that each bus and van have same number of students.

For college A-

8 vans and 8 bus were rented to ferry 240 students

No of students in 8 bus= 8y (since y students were in each bus)

No of students in 8 van= 8x (since x students were in each van)

Hence 8x+8y=240 cancelling the equation with common factor 8, the equation becomes    ⇒ x+ y=30

For College B

4 vans and 1 bus were rented to ferry 54 students

No of students in 1 bus= 1y (since y students were in each bus)

No of students in 4 van= 4x (since x students were in each van)

4x+y=54

Comparing the both equation we get and subtracting equation 2 from 1

x+y-30-4x-y-54=0  ∵ Cancelling y  

-3x=-24

∴ x=8 putting the value of x in equation 1 we get y as 22

Thus the answer is (8,22)

How you do these problems
nevsk [136]
So basically, think of a ratio as a fraction for these problems. You see the 2 numbers and you put the first one as the numerator and the second as your denominator. For example:

5 to 10

We would change this into:

\frac{5}{10}

Because the problem says to simplify, we can divide both sides by 5 and simplify it into:

\frac{1}{2}

If the problem says 5:10 instead of "5 to 10" it's the same problem just with different wording. If the numbers are labeled, the you can write the labels next to the number it corresponds with.

If you have any questions, feel free to ask down in the comments, I'll be happy to work with you!
