Sarah cut off one eighth of a 48 inch piece of ribbon Jane cutoff one nineth of a 36 peace ribbon they compared their cut pieces whose piece is longer how much longer
Answers
Sarah: 48 * 1/8 Jane: 36 * 1/9 you could do 2 things here a. solve the problem by multiplying the two "fractions" together for each person to get a number, and the larger number means the larger piece or b. take a step back and look at it piece by piece first lets compare Sarah has a piece of Ribbon equal to 48 inches while Jane's ribbon is only 36 inches in length so Sarah has the most ribbon to start out with now lets compare the two fractions 1/8 and 1/9 the smaller the denominator the bigger the number actually is because the denominator just means "divided by" this number, so the smaller the number, the less "groups" the numerator is being split up into. now in that case, 1/8 is the bigger fraction, and this fraction belongs to Sarah now if Sarah has the larger Ribbon and the larger fraction, then she automatically has the larger ribbon.
however, in this problem it asks for "how much longer" so we have to treat each of the numbers for each person as if it was a fraction 48 inches for Sarah and 36 inches for Jane will be over 1, showing that it is 48 and 36 "wholes" or whole numbers 48/1 and 36/1 now we multiply 48/1 by 1/8 because that i how much ribbon sarah needs multiply the numerator by the numerator and the denominator by the denominator 48/1* 1/8 = 48/8 or simplified to 6/1 or 6 inches of ribbon for Sarah do the same for Jane 36/1 * 1/9 = 36/9 or simplified to 4/1 or 4 inches of Ribbon for Jane therefore we can conclude Sarah has 2 more inches of Ribbon than Jane
Pls explain how to solve this 15-3n=n-1
Answers
First you have to isolate the variable. That means you have to get all the terms with the letter (n) on one side of the equal sign and everything else on the other side. To do this: First add 3n to both sides and get: 15=4n-1 Now you have to add 1 to both side and get: 16=4n Now you have to divide both sides by 4. You get the answer of: 4=n
