Question

0,25+x=5,2 0,052:x=0,13

Answer 1

0,25 + х = 5,2

х = 5,2 - 0,25

х = 4,95

0,052 : х = 0,13

х = 0,052 : 0,13

х = 0,4

Answer 2

$0.25 + x = 5.2 \\ x = 5.2 - 0.25 \\ x = 4.95 \\ \\ 0.052 \div x = 0.13 \\ \frac{13}{250} \times \frac{1}{x} = 0.13 \\ \\ \frac{13}{250x} = 0.13 \\ \\ 13 = 32.5x \\ 32.5x = 13 \\ \\ x = 0.4$
