Which number produces an irrational number when added to 0.4

Mathematics

VARVARA [1.3K]3 years ago
7 0
I don't think when this number is added to any other rational number would produce an irrational number

But we do know that when 0.4 is added to an irrational number it would be irrational. 
e.g; 0.4 + pi is irrational, etc, etc
So any other irrational number would make it irrational

S_A_V [24]

Answer:

You could answer this two ways.

Step-by-step explanation:

Method 1: Set up proportion

x/40=55/100

Cross-multiply and you will get..

2200=100x

x=22

Method 2: Use decimals

As we saw in the first method, 55 percent is equal to 55/100. 55/100 is equal to 0.55.

You can multiply 0.55 and 40 to get the answer as well.

0.55 times 40 is 22.

Hope this explanation helped! ☺️

3/4 box = 12 oz

we first need to find 1/4 of a box. to do that divide both sides by 3

1/4 box = 4 oz

for a full box which is 4/4 multiply both sides by 4

1/4 x (4)  = 4 x (4) oz

4/4 ( or one whole) = 16 oz
