What the same as 1.4

liubo4ka [24]

Answer:

$\frac{7}{5}$

Step-by-step explanation:

You can make 1.4 as a fraction, and it will be the same but in a different form.

So, to make a decimal by a fraction, you make 1.4 into a whole number. 1.4 will be 14.

Now, the denominator will be 10.

So, when you simplify $\frac{14}{10}$ , which is $\frac{7}{5}$

What is the answer to 8/? + 5/? = 7/?

disa [49]

Step-by-step explanation:

well, the first solution that comes to my mind is :

8/4 + 5/1 = 7/1

2 + 5 = 7

the reason : the only numerator I can "cut" into integer pieces is 8.

5 and 7 are prime numbers.

so, it tried to keep 5 and 7 whole, and then add a part of 8 to make this equation true. and that worked right away.
