Answer:
The answers are given below.
Step-by-step explanation:
1. 4 ------ 4 ------ 4 ------ 4 = 1
⇒ (4 ÷ 4) × (4 ÷ 4) = 1
⇒[tex]$ \bigg( \frac{4}{4} \bigg ) \times \bigg( \frac{4}{4} \bigg) $[/tex] = 1
2. 4 ----- 4 ------ 4 ------ = 2
⇒ (4 × 4) ÷ (4 + 4) = 2
⇒ [tex]$ \frac{4 \times 4}{4 + 4} = \frac{16}{8} $[/tex] = 2
3. 4 ------ 4 ----- 4 ----- 4 = 3
⇒ (4 + 4 + 4) ÷ 4 = 3
⇒ [tex]$ \frac{4 + 4 + 4}{4} = \frac{12}{4} = 3 $[/tex]
4. 4 ----- 4 ----- 4 ----- 4 = 4
⇒ ((4 - 4) ÷ 4) + 4 = 4
⇒ [tex]$ \frac{0}{4} + 4 = 0 + 4 = 4 $[/tex]
5. 4 ----- 4 ------ 4 ----- 4 = 5
⇒ ((4 × 4) + 4) ÷ 4) = 5
⇒ [tex]$ \frac{16 + 4}{4} = \frac{20}{4} = 5 $[/tex]
6. 4 ----- 4 ----- 4 ------ 4 = 6
⇒ (4 + 4) ÷ 4 + 4 = 6
⇒ [tex]$ \frac{8}{4} + 4 = 2 + 4 = 6 $[/tex]
7. 4 ----- 4 ----- 4 ----- 4 = 7
⇒ 4 - (1 - 4) = 7
⇒ [tex]$ 4 - 1 + 4 = 8 - 1 = 7 $[/tex]
