A) 2/4
b) i: 2/5*1/4= 2/20=1/10
ii:(3/5*2/4)+(2/5*3/4)=(6/20)+(6/20)=3/10+3/10=6/10
c) It seems like there is a lack of information on the tree diagram so I could not answer this.
Hope this helps :)
Answer:
1/3
Step-by-step explanation:
the one on the left is 3 times larger than the one on the right. in other words, the right triangle's dimensions times 1/3 is equal to the left triangle's dimensions.
Answer:
bottom left :)
Step-by-step explanation:
% means 100 so, 1.49/100=0.0149
Answer:
The additive inverse of -4 and
is 4 and 
Step-by-step explanation:
Given numbers -4 and 
We have to find the additive inverse of the given numbers.
Additive inverse is the number added to a given number that the sum of number is equal to zero. that is 
For given number a = -4
Let number x is added to -4 so that result is 0
⇒ x = 4
Thus, additive inverse of -4 is +4.
For given number a = 
Let additive inverse be x,

⇒ 
Thus, additive inverse of
is 
Thus, the additive inverse of -4 and
is 4 and
