Answer:

True

Step-by-step explanation:

We need to verify whether 15 and 20 are the correct solution to the rule of "The difference between the 2 number is 5 and the number are in the ratio 3 : 4". Let's see,

First rule → The difference between the 2 numbers is 5

20 - 15 = 5 ⇒ Correct

Second rule → The numbers are in the ratio 3 : 4

15 : 20 ( ÷ 5 to both ratio's ) 3 : 4 ⇒ Correct

Kira reasoned that 6 1/4 - 2 3/4 = 4 2/4 because the difference between 6 and 2 is 4 and the difference between 1/4 and 3/4 is 2

xeze [42]

Yes, she is reasoning correct, because:

6 1/4 and 2 3/4 are mixed fractions and you can substract them as it shown below:

1. You must substract the fractional parts (which are: 1/4 and 3/4) of the mixed fractions. You can notice that the have the same denominator "4", so you only need write this denominaro and substract the numerators:

= (1-3)/4=-2/4

When you simplify the result, you obtain:

=-1/2

Now, you must sum the integer parts:

6-2=4

Finally, you obtain:

4 -1/2
