mrs. santos has 2/3 meter of red lace. her daughter gave her 2/3 meter of yellow lace. how many more meters of red lace does mrs. santos have than yellow lace?
Comparison oftentimes is used to determine which among or between the values are bigger, smaller or equal.
In comparing values, subtraction and division (ratio) are used. To know how much relatively bigger or smaller a value is compared to the other, you use ratio. While to know how much bigger or smaller a value is compared to the other, we simply subtract them.
Referring to the problem, it is stated that Mrs. Santos has [tex]\frac{2}{3}[/tex] meter of red lace and [tex]\frac{2}{3}[/tex] meter of yellow lace (that was given by her daughter).
The problem asks for how many more meters of red lace than yellow lace does she have. So we simply subtract the length of yellow lace from the red lace. Since the values are similar fractions, then we can conclude that the difference is equal to zero (0). But we can check by using
Difference = Red Lace – Yellow Lace
[tex]\frac{2}{3}- \frac{2}{3}=0[/tex]
This means that the length of red lace compared to the yellow lace is equal.
For you to check further if they really are equal, we divide the length of the red lace by the yellow lace. We know that the quotient of two similar fractions/values/numbers would always be equal to one. So,
Red Lace ÷ Yellow Lace
[tex]\frac{2}{3}[/tex] ÷ [tex]\frac{2}{3}[/tex] = 1
