Alexis has 32 2/5 ounces of beads. How many necklaces can she make if each uses 2 7/10 ounces of beads?

Answers

Answer 1
Answer:

Answer:

12 necklaces

Step-by-step explanation:

Given,

The total quantity of beads she has = 32(2)/(5) ounces,

Also, the quantity of beads needed for each necklace = 2(7)/(10) ounces,

Thus, the number of necklaces can be made

=\frac{\text{total quantity of beads}}{\text{quantity of beads needed for each necklace}}

=(32(2)/(5))/(2(7)/(10))

=(162/5)/(27/10)

=(1620)/(135)

=12
Answer 2
Answer: 32 2/5 ÷ 2 7/10let's turn above into improper fractions:32 2/5 ----> 162/52 7/10 -----> 27/10so,162/5 ÷ 27/10 -------> 162/5 * 10/27 = 12 necklaces

The solution of the equation 2d - 6 = 5 is _____.

Answers

If you would like to solve the equation 2 * d - 6 = 5, you can do this using the following steps:

2 * d - 6 = 5
2 * d = 5 + 6
2 * d = 11    /2
d = 11/2
d = 5 1/2

The correct result would be 5 1/2.
2d-6=5\n\nAdd\ 6\ on\ both\ sides.\n\n2d=11\n\nDivide\ by\ 2\ on\ both\ sides.\n\nd= (11)/(2)\n\nd=5(1)/(2)

\sf\ Answer:\ {\boxed{d=5(1)/(2)}}

Manny makes dinner using 1 box of pasta and 1 jar of sauce. if pasta is sold in packages of 6 boxes and sauce is sold in packages of 3 jars, what is the least number of dinners that Manny can make without any supplies leftover?
