Step-by-step explanation:
Claim:
it takes n - 1 number of breaks to break the bar into n separate squares for all integers n.
Basic case -> n = 1
The bar is already completely broken into pieces.
Case -> n ≥ 2
Assuming that assertion is true for all rectangular bars with fewer than n squares. Break the bar into two pieces of size k and n - k where 1 ≤ k < n
The bar with k squares requires k − 1 breaks and the bar with n − k squares
requires n − k − 1 breaks.
So the original bar requires 1 + (k−1) + (n−k−1) breaks.
simplifying yields,
1 + k − 1 + n − k − 1
1 - 1 + n - 1
n - 1
Therefore, we proved as we claimed that it takes n - 1 breaks to break the bar into n separate squares.
In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.
<h3>What is ratio of two numbers?</h3>
The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.
There are two tables which give the number of pints of blue and yellow that are used to make different amounts of two shades of green dye. The table is given below;
- Green #1 is made by mixing blue and yellow in a ratio of 2 : 3.
- Green #2 is made by mixing blue and yellow in a ratio of 1 : 2.
The first one has 2 parts of blue at 3 parts of yellow. In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2.
In grade two the blue part is half of the yellow part. This means that green #1 is bluer shade of green than Green # 2.
Hence, in the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.
