The smallest total number of oranges Izzy and her siblings could have picked is 120.
<h3>What is the arithmetic operator?</h3>
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 that,
Izzy and her 3 siblings ( 4 members) pick 28 and more each.
If we consider 28 then they will remain with 18 each after saving for themselves.
Now 18 × 4 = 72 which is not possible to divide into 10 for neighbors.
So,
They need to take at least 30 oranges so 20 × 4 = 80 oranges can be divided into 10 neighbors as 8 each.
Hence "The smallest total number of oranges Izzy and her siblings could have picked is 120".
