Mika taught her sister the steps for dividing a decimal by a decimal. which instructions are correct?
1. multiply the divisor by a multiple of 10 to create an integer divisor.
2. multiply the dividend by the same multiple of 10 as step 1.
3. divide, and apply the rules for dividing signed numbers.

Hi

The answer to this question is the first option:

1. Multiply the divisor by a multiple of 10 to create an integer divisor.

2. Multiply the dividend by the same multiple of 10 as step 1.

3. Divide, and apply the rules for dividing signed numbers.

Option A is the right answer.

Step-by-step explanation:

Mika taught her sister the steps for dividing a decimal by a decimal.

The correct instructions are:

1. Multiply the divisor by a multiple of 10 to create an integer divisor.

2. Multiply the dividend by the same multiple of 10 as step 1.

3. Divide, and apply the rules for dividing signed numbers.

In other words, we move decimal points of divisor to right, to make it a whole number and move decimal point in dividend the same number of places.

the answer will be the last one

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
