Using 45-in. fabric, Regan needs 2 and one fourth yd for a dress, one fourth yd of contrasting fabric for the band at the bot

Arte-miy333 [17]

Answer:

$7\dfrac14$ yards$

Step-by-step explanation:

Regan needs the following:

$2\dfrac{1}{4}$ yards for a dress

$\dfrac{1}{4}$ yards of contrasting fabric for the band at the bottom$\\4\dfrac{3}{4}$ yards for a coordinating jacket.$

Total Length of fabric needed

$= 2\dfrac{1}{4}+\dfrac{1}{4}+4\dfrac{3}{4}\\=2+4+\dfrac{1}{4}+\dfrac{3}{4}+\dfrac{1}{4}\\=6+1+\dfrac{1}{4}\\=7\dfrac{1}{4}$ yards$

The number of yards of 45-in. fabric needed is $7\dfrac14$ yards.$

Hallie bikes 1 5/8 km before lunch and 6 1/4 km after lunch. How much farther does Hallie bike after lunch than before lunch? Ex

EleoNora [17]

Answer:

4 $\frac{5}{8}$ km

Step-by-step explanation:

To find how much farther Hallie biked after lunch compared to the amount she biked before lunch, we can subtract the amounts:

6 $\frac{1}{4}-1\frac{5}{8}$

However, we can only subtract fractions that have the same denominator, so we need to convert $\frac{1}{4}$ to a fraction with a denominator of 8:

$\frac{1}{4}=\frac{2}{8}$

Now, we can't subtract 2 from 8, so we need to 'borrow' from the 6 to make the fraction larger:

$6\frac{2}{8}=5\frac{10}{8}$

Now subtract: $5\frac{10}{8}-1\frac{5}{8}=4\frac{5}{8}$

For all real numbers a and b, a+b=b+a

This is the "commutative property of addition." The order in which you add numbers together doesn't matter, and doesn't change your final results.
