Answer:

When dividing fractions, you must have the fractions in a/b form, you must flip the second fraction, then you must change the division sign to multiplication.

To solve the first problem, 1/2 ÷ 3/4, here are the steps:

Step 1: Make sure both fractions are in a/b form, in this case they are

Step 2: Flip the second fraction: so basically we're turning 3/4 into 4/3

Step 3: Change the division sign to multiplication

Step 4: Solve

1/2 • 4/3 = 4/6 = 2/3

To solve the second problem, follow these steps

Step 1: Make sure both fractions are in a/b form, we need to turn 1 1/3 into the improper fraction 4/3. The second fraction does not need to be changed because it is already in a/b form

Step 2: Multiply Across:

4/3 • 3/4 = 12/12 = 1

Combine the like terms to create an equivalent expression: 2s+(−4s)=?

Sergeeva-Olga [200]

Answer:

$2s+\left(-4s\right)=-2s$ is the equivalent expression as $2s+\left(-4s\right)$ is equal to $-2s$ .

Step-by-step explanation:

Considering the expression

$2s+\left(-4s\right)$

As we know that

Like terms are said to be the terms which hold the same variables raised to the same power.

For example, $3x$ and $2x$ are like terms as they contain the same variable $x$ raised to the same power.

Lets solve the expression

$2s+\left(-4s\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$2s-4s$

$\mathrm{Add\:similar\:terms:}\:2s-4s=-2s$

$-2s$

Therefore,

$2s+\left(-4s\right)=-2s$ is the equivalent expression as $2s+\left(-4s\right)$ is equal to $-2s$ .

Emilio’s family volunteers at the local soup

Mice21 [21]

Answer:

Emilio will have both activities again on the same day after 90 days from this Saturday.

Step-by-step explanation:

To solve this question list the multiples of 30 and 9 to find the first common multiple because the two activities will happen again in a number divisible by both 30 and 9.

∵ The multiples of 30 are: 30, 60, 90, 120, ............

∵ The multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, .....

→ The common multiple is 90

∴ The common multiple of 30 and 9 is 90

→ That means the activities will meet again after 90 days from

this Saturday

Emilio will have both activities again on the same day after 90 days from this Saturday.
