What is the equivalent fraction? Drag the answer into the box to match the decimal. 0.7¯ ​799​​79​​70100​​711​
Vesna [10]
The equivalent fraction for 0.7 is 70/100.
 
You know this because 0.7 is the same as 7/10.

7/10 is the same as 70/100 when we create 7 groups of 10 (numerator) and 10 groups of 10 (denominator).

Also, placing a zero to the right of any number on the right hand side of the decimal point will not change the value.

0.70 is 70/100

A rectangle has an area of 20 square feet a similar rectangle has an area of 180 square feet what is ratio of the areas of these
Evgen [1.6K]

Answer:

The ratio of the areas of the smaller rectangle to the larger rectangle is  \frac{1}{9}

Step-by-step explanation:

we know that

if two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> the area of the smaller rectangle

y----> the area of the larger rectangle

so

z^{2}=\frac{x}{y}

substitute the values

z^{2}=\frac{20}{180}

simplify

z^{2}=\frac{1}{9}

That means, the area of the larger rectangle is 9 times the area of the smaller rectangle

z=\frac{1}{3} ------> the scale factor

That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle

Answer:

Option 1

Step-by-step explanation:

The shaded area is 2/3 and it is divided into 1/9 pieces. So, 2/3 divided by 1/9 which equals 6 pieces. The only equation that matches this is option 1.
