\dfrac{4}{10} +  \dfrac{28}{100} =  \dfrac{4 \times 10 }{10 \times 10} +  \dfrac{28}{100} =  \dfrac{40}{100} +  \dfrac{28}{100} = \dfrac{40+28}{100} = \dfrac{68}{100}  =\dfrac{68 \div 4}{100 \div 4}= \dfrac{17}{25}

Hi there!

4/10 = (4*10)/(10*10) = 40/100

40/100 + 28/100 = 68/100

68/100 = 34/50 = 17/25

Hope this helps!

PLZ HURRY IT'S URGENT!!

Answer:

n + 6 = 7n

Step-by-step explanation:

"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.

n − 6 = 7n is not right because the statement says the sum of a number and six.

7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.

n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.
