Answer:

2.46×10^8

Step-by-step explanation:

The decimal point is here

246000000.

Then it must be moved up to here

2.46000000

Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8

Then you have

2.46×10^8

Answer:

4 5/12 feet tall

Step-by-step explanation:

3/4  becomes 9/12

1/3 becomes 4/12

9 - 4 = 5

5/12

5 5/12

Answer:

1 5/12

Step-by-step explanation:

To subtract fractions, we must find a Common Denominator for the two fractions.

We can find a common denominator simply by multiplying the denominators by eachother.

4*3=12

3*4=12

Now we also have to multiply the numerator by what the denominator was multiplied by, so everything is equal.

3*3=9 so 9/12

1*4=4 so 4/12.

If Leons brother is 4 and 9/12 tall, we can multiply the denominator by the whole number and add it to the numerator to get an improper fraction. This makes it possible to subtract.

4*12=48 and dont forget to add the extra 9! Leons brother is 57/12 tall. Now just subtract.

57/12-4/12=53/12 or 4 and 5/12.

Leon is 4 and 5/12 tall.

Hope this helps!
