How would you multiply fractions to whole numbers?
kvv77 [185]
You could just multiply the whole number with the numerator and then divide the answer by the denominator. Or you could write the whole number over 1, and then simplify the numbers before multiplying straight across. 

2/3 x 36
2/3 x 36/1
2/1 x 12/1  (simplified the 3 and the 36)
24/1=24  (just multiplied across)

PLEASE SOMEONE HELP ASAP!!
kvv77 [185]

Answer:

Step-by-step explanation:

students = x

non-students=y

x+y=410

y=410-x

3x+7y=1650

 

3x+7(410-x)=1650

3x+2870-7x=1650

-4x=-1220 (divide both sides by -4)

x=305 y=410-305=105

Hence, 305 students attended and 105 non-students attended

Marylou buys a package of 50 jewels to decorate 4 different pair of jeans.She uses the same number of jewels on each pair of jea
Molodets [167]

She can use 12 jewels for each pair of jeans. In fact, using 12 jewels per jeans implies that she will use 12 \cdot 4 = 48 jewels. The two remaining jewels can't be used on any pair of jeans, otherwise she wouldn't use the same number of jewels for each jeans.

This derives from the fact that, if you divide 50 by 4, you get a result of 12 with a remainder of 2.
