Answer:
So the answer is [tex](7+\frac{1}{7} )\times (7+7)=100[/tex]
Step-by-step explanation:
Given,
Using [tex]7[/tex] four times and [tex]1[/tex] one time getting to [tex]100[/tex]
If we are write this way then easily get the answer;
[tex](7+\frac{1}{7} )\times (7+7)[/tex]
Add together [tex]7+\frac{1}{7}[/tex] by making a common denominator of [tex]7[/tex] and also add [tex](7+7)[/tex] in the second set of parenthesis to yield [tex]14[/tex]
[tex](\frac{49+1}{7} )\times 14[/tex]
[tex]\frac{50}{7} \times 14[/tex]
[tex]50\times 2[/tex] (By Cross-reduce and multiply the fractions)
[tex]100[/tex]
∴ [tex](7+\frac{1}{7} )\times (7+7)=100[/tex]
