Make them have a common denominator. 4/5 becomes 32/40 and 5/8 becomes 25/40.

4/5 is greater.

I Belive It's 4/5 Because My Teacher Taught Me That " The Smaller Denominator The Bigger " And With The Denominator Being 5 And 8 The Five Will Be Greater Because " The Smaller The Number The Greater The Greater The Shape .

Hopes This Helps :)

Mei Su had 80 coins. She gave most of them to her friends in such a way that each of her friends got at least one coin and no tw

Mama L [17]

Answer: 12 friends.

Step-by-step explanation:

the data we have is:

Mei Su had 80 coins.

She gave the coins to her friends, in such a way that every friend got a different number of coins, then we have that:

The maximum number of friends that could have coins is when:

friend 1 got 1 coin

friend 2 got 2 coins

friend 3 got 3 coins

friend N got N coins

in such a way that:

(1 + 2 + 3 + ... + N) ≥ 79

I use 79 because "she gave most of the coins", not all.

We want to find the maximum possible N.

Then let's calculate:

1 + 2 + 3 + 4 + 5 = 15

15 + 6 + 7 + 8 + 9 + 10 = 55

now we are close, lets add by one number:

55 + 11 = 66

66 + 12 = 78

now, we can not add more because we will have a number larger than 80.

Then we have N = 12

This means that the maximum number of friends is 12.

What is the solution to the equation? √2x+10−6=2 *Picture of the Problem Below*

Klio2033 [76]

Answer:

x = 27

Step-by-step explanation:

Given

$\sqrt{2x+10}$ - 6 = 2 ( add 6 to both sides )

$\sqrt{2x+10}$ = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

Explain how the commutative property of addition,the Associative property of addition and mental math can help you find 75.2+(57

4vir4ik [10]

Answer: The sum of 75.2+(57.376+24.8) is 157.376.

Explanation:

The commutative property of addition states that,

$a+b=b+a$

The associative property of addition states that,

$a+(b+c)=(a+b)+a$

The given expression is 75.2+(57.376+24.8).

First use commutative property of addition in the parenthesis.

$75.2+(57.376+24.8)=75.2+(24.8+57.376)$

Now use associative property of addition.

$75.2+(24.8+57.376)=(75.2+24.8)+57.376$

Now simplify the expression,

$(75.2+24.8)+57.376=100+57.376$

$(75.2+24.8)+57.376=157.376$

Therefore, the sum of 75.2+(57.376+24.8) is 157.376.
