If you multiply a number by 1, you get the same number, right? 2/2 is equal to 1, right? so, 4/7 * 2/2 = 4/7, because you're just multiplying 4/7 by 1.
$\frac{4}{7} * \frac{2}{2} = \frac{4*2}{7*2} = \frac{8}{14}$
by multiplying by a fraction that was equivalent to 1, you made an equivalent fraction. in other words, you multiplied the top and the bottom by the same number.
so:
4/7
= 8/14
= 12/21
= 16/28
et cetera

Answer from: levicorey846

All you do to get equivalent fractions is that you either multiply the denominator and numerator by the same number or you divide the denominator and numerator by the same number. so in this case, since 4 and 7 aren't factors of each other it'd be easier to multiply. for THREE equivalent fraction you multiply 3 different numbers by 4 and 7. e.g. multiply with the number 2: 4(2)/7(2)
8/14
multiply with the number 3: 4(3)/7(3)
12/21
multiply with the number 4: 4(4)/7(4)
16/28
therefore 8/14, 12/21, and 16/28 can be three equivalent fractions of 4/7
hope it helped :)

Answer from: Quest

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
