Answer:
6 : 1
Step-by-step explanation:
A unit rate has to be "a number to 1" or "x:1". Here we have a number to 1/4. Multiply both numbers by 4 so the 1/4 becomes 1.
3/2 * 4 = 12/2 = 6
1/4 * 4 = 1
3/2 : 1/4 is the same as 6 : 1
There are 6 sides, with 6 numbers. A number less than 5 is 4/6, or simplified, 2/3.
Answer: No, she does not have enough.
Step-by-step explanation:
1. You have the following information given in the problem above:
- The measures of the three pieces are: 32 centimeters, 41.19 centimeters and 57.8 centimeters long.
- She need 200 centimeters of ribbon for the box.
2. Therefore, you must add the measures given in the problem to know if Marie has enough ribbon to decorate the gift box. Then:

3. As you can see:
130.99 cm<200 cm
Therefore, she does not have enough ribbon.
One way to solve the system is to <u>substitute</u> a variable.
<u>Explanation:</u>
One approach to solve an equation is by substitution of one variable. Right now, a condition for one factor, at that point substitute that arrangement in the other condition, and explain. All value(s) of the variable(s) that fulfills a condition, disparity, arrangement of conditions, or arrangement of imbalances.
The technique for tackling "by substitution" works by settling one of the conditions (you pick which one) for one of the factors (you pick which one), and afterward stopping this go into the other condition, "subbing" for the picked variable and fathoming for the other. At that point you back-explain for the principal variable.
Answer:

Step-by-step explanation:
Each of the equations represents equivalent fractions except the one in choice C.
13/20 = 26/40, not 25/40.

<em>Comment on equal sign</em>
IMO, one should never use an equal sign where things are not equal--unless there is a clear indication you understand they are not equal. The equal sign should be regarded as a sacred symbol, with very specific rules as to its meaning and use.
