Change<br>2.215(1 and 5 are recurring/repeating decimals)<br>in form of a/b

Romashka-Z-Leto [24]

Answer:

Answer:

2.215=2 43/200

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

2.215=2.215/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

2.215/1×1000/1000=2215/1000

Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2215÷5/1000÷5=443/200

Simplify the improper fraction,

=2 43/200

In conclusion,

2.215=2 43/200

Apply the distributive property to create an equivalent expression 1/3(3j+6) what the answer

Anna71 [15]

Answer:

$\large\boxed{\dfrac{1}{3}(3j+6)=j+2}$

Step-by-step explanation:

The distributive property: <em>a(b + c) = ab + ac</em>.

$\dfrac{1}{3}(3j+6)=\left(\dfrac{1}{3\!\!\!\!\diagup_1}\right)(3\!\!\!\!\diagup^1j)+\left(\dfrac{1}{3\!\!\!\!\diagup_1}\right)(6\!\!\!\!\diagup^2)=1j+(1)(2)=j+2$
