Answer:
Diego is correct.
He has correctly divided 1 in groups of 
.
Step-by-step explanation:
The question 'How many groups of 5/6 are in 1?' means that we need to divided 1 into groups of 
.
When we form groups from a given total, we divided the total by the size of the group.
If we are dividing 
number of people in groups of 
number of people, then the expression to find the number of groups formed can be given as:
⇒ 
For this question the data given is:
So, the number of groups formed can be given as:
⇒ 
When divisor is a fraction, then we multiply the reciprocal of the divisor with the dividend.
⇒ 
⇒ 
In order to convert fraction to mixed number we will divide numerator with denominator and then write the quotient as whole number, remainder as numerator and the denominator remains as it is.
On dividing 6 by 5, the quotient =1 and remainder =1. Thus the mized number is:
⇒ 
Thus, there are or groups in 1. This matches with Diego's answer and hence he is correct.
I think its the third one
Answer:
Step-by-step explanation:
First, you gotta work out the hypotenuse of ABC, which is AC.
To do that, you need to figure out the scale factor between the two right-angled triangles. You can do that for this question because this is a similar shapes question.
12.5/5 = 2.5
The scale factor length between the two triangles is 2.5.
You can use 2.5 now to work out AC, so AC would be 13 x 2.5, which gives 32.5.
Now that you've got the hypotenuse and BC of ABC, you can use Pythagoras's theorem to work out the length of AB
Pythagoras's theorem = 
a = BC = 12.5
b = AB = we need to work this out
c = AC (the hypotenuse we just worked out) = 32.5
Let's both simplify and rearrange this at the same time so that we have our b on one side.
= 1056.25 - 156.25
b = 
b = 
b = AB = 30 We've found b or AB, now we can work out the perimeter of ABC.
Perimeter of ABC = AB + BC + AC
= 30 + 12.5 + 32.5
= 75 Here's the perimeter for ABC.
