20÷ 4 ? 3/4 ÷ (1/2)
use this <> and =
please i need help ¨p
20 / 4 = ?
(3/4) / (1/2)
(3/4) * (2/1) = 6/4 = 1 1/2
To solve the given expression, we will follow the order of operations (also known as PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's start with the first part of the expression: 20 ÷ 4.
To perform division, we divide the numerator (20) by the denominator (4). The symbol "/" represents division.
So, 20 ÷ 4 = 5.
Using the <> and = symbols, we can write this as: 20 ÷ 4 = 5.
Now, let's move to the second part of the expression: 3/4 ÷ (1/2).
To divide fractions, we follow a specific rule: when dividing fractions, we can rewrite the expression as multiplying by the reciprocal of the second fraction.
So, 3/4 ÷ (1/2) can be rewritten as 3/4 * (2/1).
Now, we can multiply the numerators and denominators separately:
Numerator: 3 * 2 = 6
Denominator: 4 * 1 = 4
So, the result is 6/4.
However, it is always better to simplify fractions if possible. In this case, the numerator and the denominator have a common factor of 2, so we can simplify the fraction further:
6/4 = (6 ÷ 2) / (4 ÷ 2) = 3/2.
Using the <> and = symbols, we can write this as: 3/4 ÷ (1/2) = 3/2.
So, the final answer to the expression is:
20 ÷ 4 = 5, and
3/4 ÷ (1/2) = 3/2.
Using the <> and = symbols together, we can write the entire expression as:
20 ÷ 4 = 5, and 3/4 ÷ (1/2) = 3/2.
