Reduce then calculate 7/8 x 4/15 x 3/7 = ? <br><br> Can you help?

Zepler [3.9K]

since this is a multiplication, all the numerators are just factors of the product numerator and all denominators are just factors of the product denominator, so we can simply reorder them some, without changing the product.

$\bf \cfrac{7}{8}\times \cfrac{4}{15}\times \cfrac{3}{7}\implies \cfrac{7}{7}\times \cfrac{4}{8}\times \cfrac{3}{15}\implies \cfrac{1}{1}\times \cfrac{1}{2}\times \cfrac{1}{5}\implies \cfrac{1\cdot 1\cdot 1}{1\cdot 2\cdot 5}\implies \cfrac{1}{10}$

Math definitely isn't my greatest subject, if anyone knows how to do this and can explain it to me please help!

Law Incorporation [45]

Answer:

y-1 = 5/3(x-3)

Choice C

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

(3,1) (6,6)

m = (6-1)/(6-3)

m = (5/3)

the point slope form of a line is given by

y-y1 = m(x-x1)

You have point (3,1)

y-1 = 5/3(x-3)

Choice C
