Which of the following expressions has a sum of 42/100

Step-by-step explanation:

Verify each expression

case 1) we have

Multiply the first term by 10/10

Remember that

Fractions with the same denominator, you can add the numerators and write the sum over the common denominator

so

therefore

case 2) we have

Multiply the second term by 10/10

Remember that

Fractions with the same denominator, you can add the numerators and write the sum over the common denominator

so

therefore

case 3) we have

Multiply the second term by 10/10

Remember that

Fractions with the same denominator, you can add the numerators and write the sum over the common denominator

so

therefore

case 4) we have

Multiply the first term by 10/10

Remember that

Fractions with the same denominator, you can add the numerators and write the sum over the common denominator

so

so

This expression is the answer

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
