Answer:

Hi! For the first question, the property being demonstrated is the Commutative Property of Addition. For the second problem, the answer would be the Additive Identity Property of 0.

Step-by-step explanation:

In the problem 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7, we can see the commutative property being used. The Commutative Property of Addition states that changing the order of the addends will not have an affect on the sum. As long as you still keep the same addends, the sum will always remain the same regardless of the order.

In the problem 16 + 0 = 16, we see the Additive property of 0 being demonstrated. This property basically states that adding a number to 0 will give you the same number. It is usually very easy to identify if you look for 0 being added to an addend.

What is 1 7/8 times 5/6

hoa [83]

$Solution, 1\frac{7}{8}\cdot \frac{5}{6}=1\frac{9}{16}\quad \left(\mathrm{Decimal:\quad }\:1.5625\right)$

$Steps:$

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 1\frac{7}{8}=\frac{15}{8}, =\frac{15}{8}\cdot \frac{5}{6}$

$\mathrm{Cross-cancel\:common\:factor:}\:3, =\frac{5}{8}\cdot \frac{5}{2}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}, =\frac{5\cdot \:5}{8\cdot \:2}$

$\mathrm{Multiply\:the\:numbers:}\:5\cdot \:5=25, =\frac{25}{8\cdot \:2}$

$\mathrm{Multiply\:the\:numbers:}\:8\cdot \:2=16, =\frac{25}{16}$

$\mathrm{Convert\:improper\:fractions\:to\:mixed\:numbers}:\quad \frac{25}{16}=1\frac{9}{16}, =1\frac{9}{16}$

Hope this helps!!!

Answer:

Quadrant II

Step-by-step explanation:

The y coordinate is positive so the quadrant is either 1 or 2

To make both happen, it must be in quadrant 2

Mr.George divided his money in the ratio 2:6 between Evan and ricky.Evan got the smaller amount of $420. How much did ricky rece

Gemiola [76]

Ratios are like fractions in the way that you can simplify them if they have common factors.
we can simplify this ratio to
1:3
that means that the bigger part got 3 times the amount of the smaller part. The problem says that Evan got the smaller amount, so if we multiply the smaller amount by 3 we should and will get the bigger amount. It says that $420 is the smaller part.
420*3=1260
so the bigger amount of money is $1260
So, because Ricky got the bigger part of Mr. George's money, he must have received
$1260
