Write a fraction equivalent to 3/5 that has a denominator of 100.
yuradex [85]

Answer:

60/100

Step-by-step explanation:

We know that 20 goes into 100 5 times, so we multiple numerator and denominator by 20 to get an equivalent fraction:

\frac{3}{5} (\frac{20}{20} )=\frac{3(20)}{5(20)} =\frac{60}{100}

Answer:

D. Subtraction property of equality

B. 6.5

Step-by-step explanation:

First blank:

The equation is x + 6.5 = 13.

To solve the equation, you want x alone on the left side, showing "x = some number." Since 6.5 is being added to x, you need to SUBTRACT 6.5. You must do the same operation to both sides of an equation, so you need to SUBTRACT 6.5 from both sides of the equation. What allows you to subtract the same number from both sides of an equation is the

<em>D. Subtraction property of equality </em>

Second blank:

Subtract 6.5 from both sides.

x + 6.5 = 13

x + 6.5 - 6.5 = 13 - 6.5

x = 6.5

<em>Answer: B. 6.5</em>

Grace and Zoe like to jump rope grades jump 66 times a minute Zoe jumps 56 times a minute they both Count Their jumps today and
san4es73 [151]

Answer:

Grace jumps for 9 minutes.

Zoe jumps for 12 minutes.

Step-by-step explanation:

Let the time for which Grace jumps the rope = x minutes

Let the time for which Zoe jumps the rope = y minutes

As per question statement:

x+y=21 ..... (1)

Number of times Grace jumps in one minute = 66

Number of times Zoe jumps in one minute = 56

Number of times Grace jumps in x minutes = 66

Number of times Zoe jumps in y minutes = 56

As per question statement:

66x+56y=1266 ...... (2)

Multiplying equation (1) with 66 and subtracting equation (2) from it:

10y = 1386 - 1266\\\Rightarrow 10y=120\\\Rightarrow  y =\bold{12\ min}

By equation (1):

x=21-12=\bold{9\ min}

Therefore, the answer is:

Grace jumps for 9 minutes.

Zoe jumps for 12 minutes.

laiz [17]

Answer:

Therefore the Equation and missing value is

\dfrac{3}{4}=\dfrac{1}{6}+x      .............Equation for the Diagram

x=\dfrac{7}{12}

Step-by-step explanation:

Given:

Let Label the Diagram such that

AB =\dfrac{1}{6}

BC =c

AC =\dfrac{3}{4}

To Find:

Equation =?

x = ?

Solution:

Here Total Length is given in Two Parts

one\ part =\dfrac{1}{6}

Second\ part =x

Total =\dfrac{3}{4}

For a Line A-B-C

AC =AB+BC       ..............Line Addition Property

Substituting the values we get

\dfrac{3}{4}=\dfrac{1}{6}+x ...Equation for the Diagram

x = \dfrac{3}{4}-\dfrac{1}{6}\\\\x=\dfrac{18-4}{4\times 6}\\\\x=\dfrac{14}{24}\\\\x=\dfrac{7}{12}

Therefore the Equation and missing value is

\dfrac{3}{4}=\dfrac{1}{6}+x ...Equation for the Diagram

x=\dfrac{7}{12}
