Respuesta :
so we have 2 large windows, each needing 3 3/4 yds of fabric....and 3 small windows, each needing 1 1/3 yds of fabric
2(3 3/4) + 3(1 1/3) =
2(15/4) + 3(4/3) =
30/4 + 12/3 =
7 1/2 + 4 =
11 1/2 (or 11.5) yds of fabric are needed <==
2(3 3/4) + 3(1 1/3) =
2(15/4) + 3(4/3) =
30/4 + 12/3 =
7 1/2 + 4 =
11 1/2 (or 11.5) yds of fabric are needed <==
Marys need a total of 23/2 yard of fabric for his all windows.
What is the arithmetic operator?
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given,
Fabric required in 1 larger window = 3 3/4
⇒ [(4×3)+3] /4 = 15/4
Fabric required in 1 smaller window = 1 1/3
⇒ (3+1)/3 = 4/3
Now,
Mary has 2 larger windows and 3 smaller
So,
Total fabric = 2 Larger + 3 smaller
Total fabric = 2(15/4) + 3(4/3)
Total fabric = 15/2 + 4
Total fabric = 23/2
Hence "Marys need a total of 23/2 yard of fabric for his all windows".
