Whats the improper fraction for 3 4/17

Answers

Answer: 55/17

Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator by the whole number, then add the numerator.

So here we multiply the denominator (17) by the whole number (3), then we add the numerator which is 4.

Finally, we put our new number over our old denominator and we have our answer 55/17.

Therefore, 3 and 4/17 can be rewritten as the improper fraction 55/17.

PLEASE HELP!! Angelo and Jimmy went shopping. Angelo had a. dollars in his wallet. He spent 1/3 of that money on new jeans. Jimmy had j. dollars in his wallet. He spent 1/2 of that money on a new jacket. Jimmy had more money left than Angelo. Which expression shows the difference between the amounts of money, in dollars, that each boy had left.

Answers

Okay, so Angelo had a dollars and spent 1/3 of that. So he spent 1/3a

Then, the amount he has left can be denoted as: (a - 1/3a)

Jimmy had j dollars and spent 1/2 of it:

So the amount he has left can be denoted as (j - 1/2j)

Since jimmy had more money left, you would subtract the amount angelo has from the amount that jimmy has left.

So: (j - 1/2j) - (a - 1/3a).

Lets solve this step by step.A is not a positive because (-9)*8=-72.B if positive because -12*(-3)=36. A negative times a negative is a positive.C is also a positive because (-2/5)*(-4) is a positive.D is not a positive because like A, one is negative and the other number is positive. A negative times a positive is a negative.I hope it helped!

We need to solve this by looking at each answer choice.

A. $- (w)/(9)=8$

To solve for w, we need to multiply by -9 on both sides.

So, $-(w)/(9) * -9 = 8 * -9\n\nw = -72$

This is not a positive solution. So eliminate A.

B. $(-12) = (y)/((-3))$

To solve for y, we need to multiply by -3 on both sides.

So, $(-12) * (-3) = (y)/((-3)) * (-3)\n\ny = 36$

This is a positive solution. This is one of our answers.

C. $[tex]-4* (-5)/(2)= -(2)/(5)z* -(5)/(2)\n\nz = 10$ [/tex]

We need to multiply by -5/2 on both sides to solve for z.

This is a positive solution. This is one of our answers.

D. $(1)/(7)x = -2$

We need to multiply by 7 on both sides to solve for x.

So, $(1)/(7) x * 7 = -2 * 7\n\nx = -14$

This is a negative solution. So this is not the answer.

So your final answer is B and C.

This will be the last prob for today but thx soo much for helping
