5/10+3/10

Answers

Rules in adding fractions:

1) Make sure that they have common denominator.
5/10 + 3/10

2) Since both fraction have a denominator of 10, add the numerator and place the sum above the denominator

5/10 + 3/10 = (5 + 3)/10 = 8/10

3) Simplify the fraction
8/10 can still be simplified into 4/5

8 ÷ 2 = 4
10 ÷ 2 = 5

5/10 + 3/10 = 4/5
add 5+3= 8    then to make it in simplest form divide it by 2 until you can't

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 3 pieces of ribbon that are each 1 dekameter long, how many 1-meter pieces of ribbon can he cut?

Answers

Answer: There are 30 1-meter pieces of ribbon he can cut.

Step-by-step explanation:

Since we have given that

Number of pieces of ribbon = 3

Length of each ribbon = 1 decameter

So, we know that

1\ decameter=10\ meter

So, Total length of 3 pieces of ribbon is given by

3* 10\n\n=30

So, Number of 1- meter pieces of ribbon he can cut is given by

(30)/(1)=30
A dekameter is = to 10 meters,
10x3=30
30÷1=30
Glenn can make 30 ribbon key chains.

Solve for y.

y/9=4 2/3

Answers

Here is how I would solve this just take 9*4 2/3 (which would be .6 repeating as a decimal as 2/3=.6 (repeating))=41.4 and 41.4/9=4.6 or 4 2/3.

6a+b = 4
5a + 2b = 1

Answers

The value of the unknown variables a and b in given equations are 1 and -2 respectively.

What is equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given are two equations,

6a+b = 4......(i)

5a + 2b = 1.......(ii)

Solving them by using substitution method,

6a+b = 4

b = 4-6a......(iii)

Using equation (iii) in equation (ii)

5a + 2(4-6a) = 1

5a+8-12a = 1

-7a = -7

a = 1

Put a = 1 n eq(iii)

b = 4-6·1

b = 4-6

b = -2

Hence, The value of the unknown variables a and b in given equations are 1 and -2 respectively.
