When multiplying fractions you multiply the denominators by the denominators and the numerators by the numerators
For example
4/5x 2/3
8/15

Of course!

First, you'll need to line up both of your fractions, there's no need to have common denominators because you'll be multiplying straight across.

Next, multiply both numerators together straight across, then denominators.

4·2= 8

5·3= 15

Most fractions will need simplified after you've multiplied your fractions, but your product (8/15) doesn't need simplified since there's no common factors with 8 and 15, or a relationship.

Answer: 8 / 15

Suppose you are starting your own company selling chocolate covered strawberries. You decide to sell the milk chocolate covered

lidiya [134]

Answer:

Step-by-step explanation:

Let $x_m$ and $x_w$ be the production level of milk and white chocolate-covered strawberries respectively. According to the given data, we know the total profit will be

$P(x_m,x_w)=$2.25x_m+$2.50x_w$

The restrictions can be written as

$x_m+x_w \leq 800$

$x_w\leq x_m/2$

$x_w\leq 200$

All the restrictions can be plotted in the same graph to find the feasible region where all of them are met. The graph is shown in the image below

The optimal solution will be the level of production such that

* All restrictions are met

* The total profit is maximum

The optimal level of production can be found in (at least) one of the vertices of the feasible region. We'll try each one as follows

P(0,0)=0

P(400,200)=$2.25 (400)+$2.50 (200) = $1400

P(600,200)=$2.25 (600)+$2.50 (200) = $1850

P(800,0)=$2.25 (800)+$2.50 (0) = $1800

We must produce 600 milk chocolate-covered strawberries and 200 white chocolate-covered strawberries to have a maximum profit of $1850/month

When solving the equation 2/3 b 5 = 7, you should first ? from both sides. Then you should multiply both sides by the ? of ?. Yo

Tju [1.3M]

Depends on the question...

If your question is 2/3b + 5 = 7, then follow this one
$\frac{2}{3}b + 5 = 7\\\\\sf You~ first~subtract~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~\frac{3}{2}~on~both~sides.\\\\ So...\\\\ \frac{2}{3}b + 5 - 5 = 7 - 5\\\\\frac{2}{3}b = 2\\\\\frac{2}{3}b \times \frac{3}{2} = 2 \times \frac{3}{2}\\\\b = 3$
Your final answer will be b = 3

If your question is 2/3b - 5 = 7, then follow this one
$\frac{2}{3}b - 5 = 7\\\\\sf You~ first~add~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~\frac{3}{2}~on~both~sides.\\\\ So...\\\\ \frac{2}{3}b - 5 + 5 = 7+5 \\\\\frac{2}{3}b = 12\\\\\frac{2}{3}b \times \frac{3}{2} = 12 \times \frac{3}{2}\\\\b =18$
Your final answer will be b = 18
