Answer = 201 / 20
Algebraic Expressions- An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc. For example, let us have a look at the expression 2x + 4. Thus, we can say that 2x + 4 is an example of an algebraic expression.
Here are more examples:
• 5x + 4y + 10
• 2x2y - 3xy2
• (-a + 4b)2 + 6ab
To simplify an algebraic expression, we just combine the like terms. Hence, the like variables will be combined together. Now, out of the like variables, the same powers will be combined together
Based on the given conditions, the equation form will be:
16 ¾ * (1 – 2/5)
Convert the expression into a fraction :
(16/1 + ¾) * (1 – 2/5)
Expand the fraction to get the least common denominator:
[(16*4) / (1*4) + ¾] * [5/5 – 2/5]
Write the numerators over common denominator:
[(64 + 3) / 4] * [(5 – 2) / 5]
Calculate the sum or difference:
= 67/4 * 3/5
= 201 / 20
