jess has $22 and saves $5 each week rosie has $10 and saves $8 each week how many weeks till they have the same amount of money
Lemur [1.5K]
Answer: 5 weeks

Explanation:
Jess starts with $22 and saves $5 per week, Rosie has $10 and saves $8 per week.

In order to find an equal amount of money between the two girls is by finding a common denominator.

Jess- 22, 27, 32, 37, 42
Rosie- 10, 18, 26, 34, 42

Since we found that they can both end up with $42, after a certain amount of weeks have passed, now you’ll want to count how many numbers are in each row to find the amount of weeks it took to get to an equal amount

Answer a, b and c. See image below
dlinn [17]

Answer:

a) 3/5 < 4/5

b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.

c)  \frac{7}{10} > \frac{9}{15}  <em>or</em>  \frac{7}{10}

Step-by-step explanation:

a) 3/5 < 4/5

Flip the sign and the placement of the fraction so 3/5 is less then 4/5.

b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.

c) We need to change the denominators to a common denominator to compare the size of the two fractions:

\frac{7}{10} × \frac{3}{3} = \frac{21}{30}

\frac{9}{15} ×  \frac{2}{2} = \frac{18}{30}

The common denominators of the two fractions is 30. Comparing the two fractions:

\frac{21}{30} >\frac{18}{30}  <em>or</em>  \frac{18}{30}

so we get:  \frac{7}{10} > \frac{9}{15}  <em>or</em>  \frac{7}{10}

Zak buys 6 gallons of fruit punch. He has coupons for $0.55 off the regular price of
kherson [118]

Answer:

$2.00

Step-by-step explanation:

If Zak is Buying 6 gallons, and he has a coupon for each gallon for $0.55 off, we need to first find how much he saved.

We can do this by calculating $0.55 (or 0.55) multiplied by 6. This answer is 3.30, or $3.30.

Now we add $3.30 to $8.70 to get the normal price for 6 gallons of fruit punch.

3.30 + 8.70 = 12.00, or $12.00

The normal price for 6 gallons of fruit punch is $12.00.

Now, we divide 12 by 6 to get the cost of one single gallon of fruit punch.

12/6 = 2

One gallon of fruit punch costs $2.00

Hope this helps! Have a great rest of your day! :)
