<h3>What is ratio?</h3>
  • An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0.
  • A proportion is an equation that sets two ratios at the same value.
  • In this section, the terms ratio and proportion are defined. Both ideas play a significant role in mathematics. Numerous examples where the concept of the ratio is highlighted may be found in daily life, such as the rate of speed (distance/time) or price (rupees/meter) of a substance.
  • An equation for proportion establishes the equality of the two provided ratios.
  • Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects. A ratio is indicated by the symbol
  • A fraction, like 2/5, can be used to represent a ratio. In our daily lives, we come across many comparisons, or ratios.
  • As a result, the ratio can be expressed in three distinct ways, including:
  1. a to b
  2. a : b
  3. a/b

Help Please!!!!!!!
Harrizon [31]

Answer:

Step-by-step explanation:

This is a logical question that can be d=solved thus;

To decide which decision to make,one has to calculate the amount for both methods to detrmine which is higher.

1. Using simple interest formula of ( P X R X T)/ 100

Since p  = 1500, r  = 2.5%,  T = 3

1500 x 2.5% x 3  / 100  =  1500 x 0.025 x 3 / 100

112.5 / 100 = 1.125

to find amount  = 1.125 + 1500 = 1501.25 for the three 3years.

2. Using compound interest formula of ( P ( 1 + r/n)∧nt

1 + (2%/3) ∧3(3)

1500( 0.02/3) ∧ 9

1500  x 0.006 ∧9

1500 x 2.60 = 3900

A = 3900 + 1500 = 5400

SO FROM THE ABOVE I WILL G FOR THE HIGH YIELD SAVINGS AS IT IS HIGHER THAN THE INTEREST SAVINGS
